THERMALLY STABLE NANOPARTICLES AND METHODS THEREOF RELATED APPLICATIONS [0001] This application claims priority to U.S. Patent Application Serial No. 17/661,109, filed April 28, 2022, which is incorporated herein by reference in its entirety. TECHNICAL FIELD [0002] This application generally relates to methods of stabilizing nanoparticles. More particularly, this application relates to coating nanoparticles to provide colloidal and thermal stability. BACKGROUND [0003] Owing to their unique optical properties, chemical stability, tunability and high surface-area-to-volume ratio, metal nanoparticles represent desirable materials for biomedical applications, such as sensors, wound dressings and other therapeutics (Clasky, et al., 2021). [0004] Research into thermal reshaping of nanoparticles exists primarily in the realm of academia and focuses on rod-shaped nanoparticles (i.e. nanorods). Existing strategies include coating nanorods in carbon (Khalavka, et al., Journal of Physical Chemistry C, 2007), graphene oxide (Shirshani, et al., Plasmonics, 2018), gelatin (Canpean, et al., Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2013) and silica (Chen, et al., Optics Express, 2010). Such strategies have been shown to be capable of limiting thermal reshaping at elevated temperatures. [0005] Research focusing on nanorod thermal reshaping includes polymer coating strategies. A recent study coats nanorods with poly(styrene sulfonate), poly(ethylene glycol) (PEG), poly(vinylpyrrolidone) (PVP) and phosphatidylcholine (PC) (Horiguchi, et al., 2008). The study shows that the passivating layers on the surface of nanorods influence nanoparticle reshaping dynamics. [0006] A recent publication studies thermal reshaping of gold nanorods in a polymer matrix (Kennedy, et al., ACS Applied Materials and Interfaces, 2018). The authors embed the nanorod in matrices of poly(methylmethacrylate) (PMMA) and applied high temperatures to discern their effects on reshaping. The reshaping of the nanorods was shown to be affected by the surrounding environment playing a key role in slowing surface diffusion and stabilizing the nanorod shape. [0007] An investigation into the colloidal stability of nanoparticles found that PEGylation may be effective at stabilizing the nanoparticles upon autoclaving (Masse, et al., Molecules, 2019). However, this paper only deals with spherical nanoparticles, as opposed to anisotropic particles. The paper further does not tackle the issue of thermal reshaping. [0008] A recent publication (Salih, et al., ACS Nano, 2021) demonstrates nanoparticle addition to contact lens materials prior to lens curing but only uses commercially available citrate-coated gold nanoparticles. The gold nanoparticles used in this study are spherical and represent the most thermodynamically stable product of gold nanocrystals (i.e. the morphology that minimizes surface energy to the largest extent). The integration strategy of this study (i.e. citrate coating) cannot be extended to anisotropic nanoparticles due to the high surface energy and thermal reshaping . [0009] However, improvements over prior art tools are needed. SUMMARY [0010] Disclosed herein are systems, compositions, and methods to improve stability of nanoparticles in base materials. [0011] One general aspect includes a composition for light filtering. The composition also includes a base material; a plurality of gold nanoparticles dispersed in the base material, where at least a portion of the plurality of gold nanoparticles have an anisotropic shape; a stabilizing mechanism disposed to selectively couple with at least a portion of the plurality of gold nanoparticles to enhance stability of at least the portion of the plurality of gold nanoparticles in the base material, where a molecular weight of the stabilizing mechanism is selected to control thermal reshaping of the anisotropic shape of at least the portion of the plurality of gold nanoparticles; and where the composition exhibits a peak light absorption value in the range of about 600nm to about 1000nm, and where the composition exhibits an absorption spectrum having a full-width at half maximum of about 58nm-70nm. [0012] One general aspect includes a composition for light filtering. The composition also includes a base material; a plurality of nanoparticles dispersed in the base material, where at least a portion of the plurality of nanoparticles have an anisotropic shape; a stabilizing mechanism disposed to selectively couple with at least a portion of the plurality of nanoparticles to enhance stability of at least the portion of the plurality of nanoparticles in the base material, where a molecular weight of the stabilizing mechanism is selected to control thermal reshaping of the anisotropic shape of at least the portion of the plurality of nanoparticles; and where the composition exhibits a peak light absorption value in the range of about 600nm to about 1000nm, and where the composition exhibits an absorption spectrum having a full-width at half maximum of about 58nm-70nm.

DETAILED DESCRIPTION [0017] There exists a need to develop strategies that resist or limit thermal reshaping of nanoparticles by mitigating the surface diffusion of atoms, are versatile and biocompatible for integration into a variety of applications, and are repeatable and commercially viable for easy adoption into existing manufacturing strategies. [0018] Moreover, sterilization procedures may lead to a rearranging of surface atoms of nanoparticles (NPs) to lower energy configurations in a process called thermal reshaping. As a non-limiting example, a sterilization procedure may comprise autoclaving. Such rearranging may result the shape of a sphere, which is more thermodynamically stable. This rearrangement may occur in anisotropic nanoparticles, such as rods or bipyramids that revert to spherical or icosahedral shapes upon autoclaving. This process may change the properties of the nanoparticles. Such property changing may serve to negate the work of designing a desired nanoparticle morphology. In addition to being able to withstand autoclaving, the stability of nanoparticles at elevated temperatures is crucial for work in catalysis, plasmonics, photothermal therapy, and other such related applications. [0019] In order to effectively utilize metal nanoparticles in these myriad applications, such nanoparticles must be able to withstand multiple stressors including, but not limited to, thermal and mechanical stressors. Autoclaving may refer to sterilization procedures utilizing elevated levels of stress for extended periods of time. Stress may comprise thermal or mechanical stress. Thermal stress may arise from elevated temperatures. Mechanical stress may arise from elevated pressures. Extended periods of time may comprise ranges of about 15 minutes up to about 60 minutes, though longer or shorter times may be used. As non-limiting examples, extended periods of time may range from about 20min up to about 60min, about 25min up to about 60min, about 30min up to about 60min, about 35min up to about 60min, about 40min up to about 60min, about 45min up to about 60min, about 50min up to about 60min, or about 55min up to about 60min. Elevated temperatures may range from about 20°C up to about 130°C, though other temperatures may be applied. As non-limiting examples elevated temperatures may range from about 20°C up to about 130°C, about 30°C up to about 130°C, about 40°C up to about 130°C, about 50°C up to about 130°C, about 60°C up to about 130°C, about 70°C up to about 130°C, about 80°C up to about 130°C, about 90°C up to about 130°C, about 100°C up to about 130°C, or about 110°C up to about 130°C. Elevated pressures may comprise pressures of about 290kPa and above, though other pressures may be used. As non-limiting examples, elevated pressures may comprise pressures of about 290kPa up to about 360kPa, 300kPa up to about 360kPa, 310kPa up to about 360kPa, 320kPa up to about 360kPa, 330kPa up to about 360kPa, 340kPa up to about 360kPa, or 350kPa up to about 360kPa. Due to high surface energy, the melting point of nano-sized particles is significantly lower than their bulk counterparts. [0020] The disclosure below relates to a strategy by which thermal reshaping of nanoparticles in high-stress processes may be limited. Such nanoparticles may be anisotropic. Such a strategy may comprise coating nanoparticles. Such a strategy may comprise tailoring the viscosity of a coating, rather than only exchanging coating materials. The present disclosure relates to methods using a fundamental strategy of coating layers to increase viscosity at an interface. Such an interface may comprise a nanoparticle-polymer interface. Increased viscosity at an interface may lead to a limiting of thermal reshaping. High stress may comprise mechanical stress (e.g. pressure), thermal stress, and other such known stressors. High-stress processes may comprise autoclaving, sterilization procedures, and other such known processes. The disclosure further relates to both colloidal and gel-integrated nanoparticles. Such nanoparticles may comprise shapes of either rods or bipyramids, though a broader variety of shapes to be integrated into a broader variety of applications are also enabled. The present disclosure relates to a wide- reaching method for nanoparticle integration into a variety of applications. [0021] The present disclosure relates to nanoparticles such as metal nanoparticles, and more particularly to gold nanoparticles, for example. Reference made to gold nanoparticles may be applied to other nanoparticles, including metal nanoparticles. Gold nanoparticles may comprise anisotropic shapes. An anisotropic gold nanoparticle may comprise a bipyramid shape, though other anisotropic shapes are possible. The present disclosure further relates to a stabilizing mechanism. The use of a stabilizing mechanism may enable nanoparticle resistance to thermal stressors. Such resistance may be enabled by passivating atoms on the surface of nanoparticles. Passivation may restrict nanoparticle surface atom’s tendency to revert to a sphere (the more thermodynamically stable conformation) under applied stress. Such applied stress may comprise thermal stress, mechanical stress, and other such stressors known in the art. The present disclosure relates to a stabilizing mechanism. A stabilizing mechanism may artificially increase the coordination number (e.g. creating Au-polymer bonds with Au atoms at free nanoparticle surfaces) of nanoparticle surface atoms. A stabilizing mechanism may further increase local viscosity at a nanoparticle surface. Such a surface may comprise an interface, wherein the interface may further comprise a nanoparticle-polymer interface. A combination of an increased coordination number and an increased local viscosity may facilitate a restriction in the movement of nanoparticle surface atoms. Such a restriction may maintain morphology of nanoparticles even under increased applied stress. In an aspect of the present disclosure, such increased applied stress may occur during autoclaving. Autoclave stability of gel-integrated nanoparticles may therefore be increased. [0022] The present disclosure relates to methods of producing nanoparticles such as gold nanoparticles. The present disclosure further relates to methods of engineering the shape of nanoparticles. Such shape engineering may facilitate blocking specific light ranges in the range of about 600nm up to about 1000 nm. Engineering nanoparticle shape may lead to anisotropic gold nanoparticles. Anisotropic gold nanoparticles may comprise a bipyramid shape, though other anisotropic shapes are possible. Such particles may have sharp features. Higher surface energy associated with sharper features of anisotropic gold particles may lead to thermal reshaping at high temperatures. This reshaping may result from diffusion of surface atoms to lower energy configurations. This reshaping may further require additional nanoparticle modification to imbue thermal stability. The present disclosure relates to such modification, overcoming significant barriers to commercialization. [0023] As a non-limiting example, thermal reshaping has been shown to depend on aspect ratios of rod-shaped nanoparticles due to the propensity of gold atoms at the ends of a rod to diffuse to the center under various stressors (e.g. thermal stress, mechanical stress, etc.). At high aspect ratios, a threat of Rayleigh instability also exists. Rayleigh instability may facilitate nanorods breaking into a chain of nanospheres. This may result due to the increased surface tension upon reshaping. [0024] The present disclosure relates to coating nanoparticles. Such nanoparticles may exhibit photophysical properties. Coating nanoparticles may facilitate increased nanoparticle stability. Nanoparticles may be integrated as tunable optical filters in optically transparent substrates to produce devices. Devices may comprise ophthalmic devices. However, nanoparticles may also be integrated into other devices. [0025] The present disclosure relates to a stabilizing mechanism. As a non-limiting example, a stabilizing mechanism may comprise poly(vinyl pyrrolidone) (PVP) polymer chains. Such polymer chains may comprise a range of molecular weights. A non-limiting example of a range may comprise molecular weights of about 55kDa up to about 1300kDa. Additional molecular weight ranges exist. As non-limiting examples, molecular weight ranges may comprise about 55kDa up to about 1200kDa, about 55kDa up to about 1100kDa, about 55kDa up to about 1000kDa, about 55kDa up to about 900kDa, about 55kDa up to about 800kDa, about 55kDa up to about 700kDa, about 55kDa up to about 600kDa, about 55kDa up to about 500kDa, about 55kDa up to about 400kDa, about 55kDa up to about 300kDa, about 55kDa up to about 200kDa, or about 55kDa up to about 1000kDa. Monomer units of PVP comprise nitrogen atoms with lone pairs of electrons. Such lone pairs of electrons may bind to surfaces of gold nanoparticles. Such binding may enhance colloidal stability. PVP may be attached to a nanoparticle surface by incubating the nanoparticles in a high concentration solution of PVP. Such a solution may comprise ethanol (10-20% w/v) with a small amount of sodium dodecyl sulfate (0.6% w/v in water). Incubation may occur overnight at 40°C. An increase in molecular weight of PVP attached to a nanoparticle surface may facilitate a decrease in thermal reshaping. A decrease in thermal reshaping may be measured by an observed change in the localized surface plasmon resonance peak. [0026] The present disclosure relates to methods of using increased molecular weights of stabilizing mechanisms. Such stabilizing mechanisms may comprise PVP, though other stabilizing mechanisms known in the art may be used. A method of using increased molecular weights of a stabilizing mechanism may lead to an increased viscosity at the nanoparticle- polymer surface. An increased viscosity at the nanoparticle-polymer surface may restrict movement of surface atoms and improve thermal stability of nanoparticles. [0027] The present disclosure relates to a base material. Such a base material may comprise, a biomaterial, a biomaterial matrix, a hydrogel, and other such materials known in the art. The disclosure further relates to nanoparticles. Such nanoparticles may comprise gold. Gold nanoparticles may be grown from a pentatwinned gold seed, though other methods of synthesis are known in the art. Such nanoparticles may comprise shapes. Such shapes may be anisotropic. Such shapes may be bipyramids. Alternative shapes are known in the art and may comprise, but are not limited to, cubic shape, a nanorod shape, an octahedral shape, a decahedral shape, a cuboctahedral shape, a tetrahedral shape, a rhombic dodecahedral shape, a truncated ditetragonal prismatic shape, or a truncated bitetrahedral shape. The present disclosure further relates to a stabilizing mechanism. Such stabilizing mechanism may comprise a polymer. Such polymers may comprise a variety of molecular weights. Such polymer may comprise PVP. Alternative polymers are known in the art and may comprise, but are not limited to, poly(ethylene glycol) (PEG), polycarbonate, poly(vinyl alcohol) (PVA), polyvinylpyrrolidone (PVP), polystyrene (PS), polycaprolactone (PCL), ethylene oligomers or polyethylene (PE), polypropylene (PP), and poly(methyl methacrylate) (PMMA), as well as copolymers or blends thereof. Such polymer may comprise PVP with molecular weights of about 55kDa up to about 1300kDa. The present disclosure relates to a method of coupling a gold nanoparticle to a stabilizing mechanism. Coupling may occur through chemical conjugation. Such coupling may be selective. Such coupling may enhance colloidal and/or thermal stability of a nanoparticle, as well as biocompatibility. The present disclosure relates to a composition, wherein a base material comprising nanoparticles and a stabilizing mechanism exhibits a peak light absorption in the range of about 600nm up to about 1000nm. Such peak light absorption may be tuned through tuning nanoparticle morphology. Morphology may be tuned by configuring an aspect ratio defined by a quotient of major and minor axes length, a volume, sharpness, and/or other related features. Aspect ratios may be tuned to about 1.9 up to about 2.9, though other such aspect ratios may be possible. As non-limiting examples, aspect ratios may range from about 1.9 up to about 2.8, about 1.9 up to about 2.7, about 1.9 up to about 2.6, about 1.9 up to about 2.5, about 1.9 up to about 2.4, about 1.9 up to about 2.3, about 1.9 up to about 2.2, about 1.9 up to about 2.1, about 1.9 up to about 2.0, about 2.0 up to about 2.8, about 2.0 up to about 2.7, about 2.0 up to about 2.6, about 2.0 up to about 2.5, about 2.0 up to about 2.4, about 2.0 up to about 2.3, about 2.0 up to about 2.2, or about 2.0 up to about 2.1. Volumes may be tuned to about 250nm ³ up to about 30,000nm ³ , though other such volumes may be possible. As non- limiting examples, volumes may be tuned to about 1,250nm ³ up to about 30,000nm ³ , about 2,250nm ³ up to about 30,000nm ³ , about 3,250nm ³ up to about 30,000nm ³ , about 4,250nm ³ up to about 30,000nm ³ , about 5,250nm ³ up to about 30,000nm ³ , about 6,250nm ³ up to about 30,000nm ³ , about 7,250nm ³ up to about 30,000nm ³ , about 8,250nm ³ up to about 30,000nm ³ , about 9,250nm ³ up to about 30,000nm ³ , about 10,250nm ³ up to about 30,000nm ³ , about 11,250nm ³ up to about 30,000nm ³ , about 12,250nm ³ up to about 30,000nm ³ , about 13,250nm ³ up to about 30,000nm ³ , about 14,250nm ³ up to about 30,000nm ³ , about 15,250nm ³ up to about 30,000nm ³ , about 16,250nm ³ up to about 30,000nm ³ , about 17,250nm ³ up to about 30,000nm ³ , about 18,250nm ³ up to about 30,000nm ³ , about 19,250nm ³ up to about 30,000nm ³ , about 20,250nm ³ up to about 30,000nm ³ , about 21,250nm ³ up to about 30,000nm ³ , about 22,250nm ³ up to about 30,000nm ³ , about 23,250nm ³ up to about 30,000nm ³ , about 24,250nm ³ up to about 30,000nm ³ , about 25,250nm ³ up to about 30,000nm ³ , about 26,250nm ³ up to about 30,000nm ³ , about 27,250nm ³ up to about 30,000nm ³ , about 28,250nm ³ up to about 30,000nm ³ , ^or about 29,250nm ³ up to about 30,000nm ³ . Such tuning may result in a Full-Width at Half Maximum (FWHM) value of about 58nm up to about 70nm. As non-limiting examples, FWHM values may range from about 59nm up to about 70nm, about 60nm up to about 70nm, about 61nm up to about 70nm, about 62nm up to about 70nm, about 63nm up to about 70nm, about 64nm up to about 70nm, about 65nm up to about 70nm, about 66nm up to about 70nm, about 67nm up to about 70nm, about 68nm up to about 70nm, or about 69nm up to about 70nm. [0028] Additional capabilities relating to the present disclosure exist. The present disclosure additionally relates to a variety of polymers and other such compounds known in the art that may be grafted to the surface of nanoparticles. The use of various polymers and other such compounds may enable the integration of nanoparticles into a variety of biomaterials. Such nanoparticles, may comprise a variety of shapes. The disclosure is therefore independent of a specific biomaterial. Moreover, the disclosure relates to the incorporation of a variety of shapes of nanoparticles further comprising a variety of stabilizing mechanisms into virtually any biomaterial of interest. Non-limiting examples of biomaterials may comprise hydrogel or silicone hydrogel material suitable for use in the formation of a soft contact lens. Such materials are known in the art and include Group 1—Low Water (<50% H2O) Nonionic Hydrogel Polymers (e.g., tefilcon, tetrafilcon A, crofilcon, helfilcon A, helfilcon B, mafilcon, polymacon, hioxifilcon B); Group 2—High Water (>50% H2O) Nonionic Hydrogel Polymers (e.g., surfilcon A, lidofilcon A, lidofilcon B, netrafilcon A, hefilcon B, alphafilcon A, omafilcon A, omafilcon B, vasurfilcon A, hioxifilcon A, hioxifilcon D, nelfilcon A, hilafilcon A, hilafilcon B, acofilcon A, nesofilcon A); Group 3—Low Water (<50% H2O) Ionic Hydrogel Polymers (e.g., bufilcon A, deltafilcon A, phemfilcon); Group 4—High Water (>50% H2O) Ionic Hydrogel Polymers (e.g., bufilcon A, perfilcon A, etafilcon A, focofilcon A, ocufilcon A, ocufilcon B, ocufilcon C, ocufilcon D, ocufilcon E, ocufilcon F, phemfilcon A, methafilcon A, methafilcon B, vilfilcon A); and Silicone Hydrogel Polymers (e.g., lotrafilcon A, lotrafilcon B, galyfilcon A, senofilcon A, senofilcon C, sifilcon A, comfilcon A, enfilcon A, balafilcon A, delefilcon A, narafilcon B, narafilcon A, stenfilcon A, somofilcon A, fanfilcon A, samfilcon A, elastofilcon). [0029] The present disclosure may also relate to methods of using biocompatible and gel-compatible materials to limit thermal reshaping. DEFINITIONS [0030] It is to be understood that the invention is not limited to the details of construction or process steps set forth in the following description. The invention is capable of other embodiments and of being practiced or being carried out in various ways using the teaching herein. [0031] With respect to the terms used in this disclosure, the following definitions are provided. [0032] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the invention belongs. The polymer definitions are consistent with those disclosed in the Compendium of Polymer Terminology and Nomenclature, IUPAC Recommendations 2008, edited by: Richard G. Jones, Jaroslav Kahovec, Robert Stepto, Edward S. Wilks, Michael Hess, Tatsuki Kitayama, and W. Val Metanomski. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference. [0033] As used herein, the term “(meth)” designates optional methyl substitution. Thus, a term such as “(meth)acrylates” denotes both methacrylates and acrylates. [0034] The term “individual” includes humans and vertebrates. [0035] The term “ophthalmic device” refers to any device which resides in or on the eye or any part of the eye, including the ocular surface. These devices can provide optical correction, cosmetic enhancement, vision enhancement, therapeutic benefit (for example as bandages) or delivery of active components such as pharmaceutical and nutraceutical components, or a combination of any of the foregoing. Examples of ophthalmic devices include but are not limited to lenses, optical and ocular inserts, including but not limited to punctal plugs, and the like. “Lenses” include soft contact lenses, hard contact lenses, hybrid contact lenses, intraocular lenses, and overlay lenses. The ophthalmic device may comprise a contact lens. [0036] The term “contact lens” refers to an ophthalmic device that can be placed on the cornea of an individual's eye. The contact lens may provide corrective, cosmetic, or therapeutic benefit, including wound healing, the delivery of drugs or nutraceuticals, diagnostic evaluation or monitoring, ultraviolet light filtering, visible light or glare reduction, or any combination thereof. A contact lens can be of any appropriate material known in the art and can be a soft lens, a hard lens, or a hybrid lens containing at least two distinct portions with different physical, mechanical, or optical properties, such as modulus, water content, light transmission, or combinations thereof. [0037] The ophthalmic devices and lenses described herein may be comprised of silicone hydrogels or conventional hydrogels. Silicone hydrogels typically include at least one hydrophilic monomer and at least one silicone-containing component that are covalently bound to one another in the cured device. [0038] As used herein, the terms "physical absorption" or "chemical absorption" refer to processes in which atoms, molecules, or particles enter the bulk phase of a gas, liquid, or solid material and are taken up within the volume. Absorption in this manner may be driven by solubility, concentration gradients, temperature, pressure, and other driving forces known in the art. [0039] As used herein, "adsorption" is defined as the deposition of a species onto a surface. The species that gets adsorbed on a surface is known as an adsorbate, and the surface on which adsorption occurs is known as an adsorbent. Examples of adsorbents may comprise clay, silica gel, colloids, metals, nanoparticles etc. Adsorption may occur via chemical or physical adsorption. Chemical adsorption may occur when an adsorbate is held to the an adsorbent via chemical bonds, whereas physical adsorption may occur when an adsorbate is joined to an adsorbent via weak van der Waal’s forces. [0040] As used herein, "antibacterial" means intended to kill or reduce the harmful effects of bacteria. [0041] As used herein, "colloid" refers to dispersions of wherein one substance is suspended in another. Many examples of colloids in the art contain polymers. In this aspect, polymers may be adsorbed or chemically attached to the surface of particles suspended in the colloid, or the polymers may freely move in the colloidal suspension. The presence of polymers on particles in the suspension may directly relate to "colloidal stability," wherein "colloidal stability" refers to the tendency of a colloidal suspension to undergo sedimentation. Sedimentation would result in the falling of particles out of a colloid. Polymers adsorbed or chemically attached to a particle may affect its colloidal stability. [0042] As used herein, the term "diffusion" refers to the process wherein there is a net flow of matter from one region to another. An example of such process is "surface diffusion," wherein particles move from one area of the surface of a subject to another area of the same surface. This can be caused by thermal stress or applied pressure. [0043] “Target macromolecule” means the macromolecule being synthesized from the reactive monomer mixture comprising monomers, macromers, prepolymers, cross-linkers, initiators, additives, diluents, and the like. [0044] The term “polymerizable compound” means a compound containing one or more polymerizable groups. The term encompasses, for instance, monomers, macromers, oligomers, prepolymers, cross-linkers, and the like. [0045] “Polymerizable groups” are groups that can undergo chain growth polymerization, such as free radical and/or cationic polymerization, for example a carbon- carbon double bond which can polymerize when subjected to radical polymerization initiation conditions. Non-limiting examples of free radical polymerizable groups include (meth)acrylates, styrenes, vinyl ethers, (meth)acrylamides, N-vinyllactams, N-vinylamides, O- vinylcarbamates, O-vinylcarbonates, and other vinyl groups. Preferably, the free radical polymerizable groups comprise (meth)acrylate, (meth)acrylamide, N-vinyl lactam, N- vinylamide, and styryl functional groups, and mixtures of any of the foregoing. More preferably, the free radical polymerizable groups comprise (meth)acrylates, (meth)acrylamides, and mixtures thereof. The polymerizable group may be unsubstituted or substituted. For instance, the nitrogen atom in (meth)acrylamide may be bonded to a hydrogen, or the hydrogen may be replaced with alkyl or cycloalkyl (which themselves may be further substituted). [0046] Any type of free radical polymerization may be used including but not limited to bulk, solution, suspension, and emulsion as well as any of the controlled radical polymerization methods such as stable free radical polymerization, nitroxide-mediated living polymerization, atom transfer radical polymerization, reversible addition fragmentation chain transfer polymerization, organotellurium mediated living radical polymerization, and the like. [0047] A “monomer” is a mono-functional molecule which can undergo chain growth polymerization, and in particular, free radical polymerization, thereby creating a repeating unit in the chemical structure of the target macromolecule. Some monomers have di-functional impurities that can act as cross-linking agents. A “hydrophilic monomer” is also a monomer which yields a clear single phase solution when mixed with deionized water at 25° C. at a concentration of 5 weight percent. A “hydrophilic component” is a monomer, macromer, prepolymer, initiator, cross-linker, additive, or polymer which yields a clear single phase solution when mixed with deionized water at 25° C. at a concentration of 5 weight percent. A “hydrophobic component” is a monomer, macromer, prepolymer, initiator, cross-linker, additive, or polymer which is slightly soluble or insoluble in deionized water at 25° C. [0048] A “macromolecule” is an organic compound having a number average molecular weight of greater than 1500, and may be reactive or non-reactive. [0049] A “macromonomer” or “macromer” is a macromolecule that has one group that can undergo chain growth polymerization, and in particular, free radical polymerization, thereby creating a repeating unit in the chemical structure of the target macromolecule. Typically, the chemical structure of the macromer is different than the chemical structure of the target macromolecule, that is, the repeating unit of the macromer's pendent group is different than the repeating unit of the target macromolecule or its mainchain. The difference between a monomer and a macromer is merely one of chemical structure, molecular weight, and molecular weight distribution of the pendent group. As a result, and as used herein, the patent literature occasionally defines monomers as polymerizable compounds having relatively low molecular weights of about 1,500 Daltons or less, which inherently includes some macromers. In particular, monomethacryloxypropyl terminated mono-n-butyl terminated polydimethylsiloxane (molecular weight=500-1500 g/mol) (mPDMS) and mono-(2-hydroxy-3-methacryloxypropyl)- propyl ether terminated mono-n-butyl terminated polydimethylsiloxane (molecular weight=500- 1500 g/mol) (OH-mPDMS) may be referred to as monomers or macromers. Furthermore, the patent literature occasionally defines macromers as having one or more polymerizable groups, essentially broadening the common definition of macromer to include prepolymers. As a result, and as used herein, di-functional and multi-functional macromers, prepolymers, and crosslinkers may be used interchangeably. [0050] A “silicone-containing component” is a monomer, macromer, prepolymer, cross-linker, initiator, additive, or polymer in the reactive mixture with at least one silicon- oxygen bond, typically in the form of siloxy groups, siloxane groups, carbosiloxane groups, and mixtures thereof. [0051] Examples of silicone-containing components which are useful in this invention may be found in U.S. Pat.

[0054] As used herein, the term "thermoset" refers to a property of polymers, wherein a thermoset polymer forms well-defined, irreversible, chemical networks that tend to grow in three dimensional directions through the process of curing, which can either occur due to heating or through the addition of a curing agent, therefore causing a crosslinking formation between its chemical components, and giving the thermoset a strong and rigid structure that can be added to other materials to increase strength. Once a thermoset polymer has formed networks during curing, the polymer cannot be re-cured to set in a different manner. [0055] A “homopolymer” is a polymer made from one monomer; a “copolymer” is a polymer made from two or more monomers; a “terpolymer” is a polymer made from three monomers.

Gels may also be seen as colloids in which the liquid medium has become viscous enough to behave more or less as a solid. [0063] An “interpenetrating polymeric network” comprises two or more networks which are at least partially interlaced on the molecular scale but not covalently bonded to each other and which cannot be separated without braking chemical bonds. A “semi-interpenetrating polymeric network” comprises one or more networks and one or more polymers characterized by some mixing on the molecular level between at least one network and at least one polymer. A mixture of different polymers is a “polymer blend.” A semi-interpenetrating network is technically a polymer blend, but in some cases, the polymers are so entangled that they cannot be readily removed. [0064] The terms “reactive mixture” and “reactive monomer mixture” refer to the mixture of components (both reactive and non-reactive) which are mixed together and when subjected to polymerization conditions form the conventional or silicone hydrogels of the present invention as well as contact lenses made therefrom. The reactive monomer mixture may comprise reactive components such as the monomers, macromers, prepolymers, cross-linkers, and initiators, additives such as wetting agents, release agents, polymers, dyes, light absorbing compounds such as UV absorbers, pigments, dyes and photochromic compounds, any of which may be reactive or non-reactive but are capable of being retained within the resulting biomedical device, as well as pharmaceutical and nutraceutical compounds, and any diluents. It will be appreciated that a wide range of additives may be added based upon the biomedical device which is made and its intended use. Concentrations of components of the reactive mixture are expressed as weight percentages of all components in the reactive mixture, excluding diluent. When diluents are used, their concentrations are expressed as weight percentages based upon the amount of all components in the reactive mixture and the diluent.

Some exemplary sources of UV irradiation may comprise continuous wave (CW) UV- lamps with a moderate light and pulsed lasers. [0091] As used herein, "light absorption" is defined as the phenomenon wherein electrons absorb the energy of incoming light waves (i.e. photons) and change their energy state.

The resultant absorption patterns characteristic to a given material may be displayed using an "absorption spectrum", wherein an "absorption spectrum" shows the change in absorbance of a sample as a function of the wavelength of incident light and may be measured using a spectrophotometer. Unique to an "absorption spectrum" is an "absorption peak", wherein the frequency or wavelength of a given sample exhibits the maximum or the highest spectral value of light absorption. With regards to light absorption of wavelengths of light corresponding to the visible spectrum, a material or matter absorbing light waves of certain wavelengths of the visible spectrum may cause an observer to not see these wavelengths in the reflected light.

The particles can be incorporated in varying quantities within an optically transparent substrate to achieve an optically transparent material which exhibits a desired level of light blocking at one or more wavelengths or a range of wavelengths within the electromagnetic spectrum. The percent blocking at a particular wavelength can be determined from the material's transmission spectrum, where blocking=100−percent transmission (% T). [0094] As used herein, the term "light-blocking profile" or "light-blocking spectrum" refers to the absorption spectrum of a light-blocking material. [0095] The terms "red-light blocking” or "red-light absorbing” or “red-light filtering” refer to the ability of certain particles to absorb, scatter, and/or extinguish incident light within the red region of the visible spectrum (e.g., between 620 and 750nm or between about 600 nm up to about 850 nm). Thus, the terms "red-light blocking” or "red-light absorbing” encompass particles that absorb, scatter, and/or extinguish incident light within the red region of the visible spectrum. The particles can be incorporated in varying quantities within an optically transparent substrate to achieve an optically transparent material which exhibits a desired level of red-light blocking at one or more wavelengths or a range of wavelengths within a spectral region. [0096] “Nanoparticle (NP)” as used herein refers to a particle having at least one dimension that is less than 100 nm. In some cases, nanoparticles can have at least one dimension less than 50 nm. NP's may have a variety of shapes. In some instances, NP's may have a cubic shape, spherical shape, rod shape, bipyramidal shape, an octahedral shape, a decahedral shape, a cuboctahedral shape, a tetrahedral shape, a rhombic dodecahedral shape, a truncated ditetragonal prismatic shape, or a truncated bitetrahedral shape. “Plasmonic nanoparticle” as used herein refers to a metal nanoparticle that has unique optical properties due to local surface plasmon resonance that allow them to interact with light waves. These properties are tunable by changing the shape, size, composition or medium surrounding the nanoparticle's surface. It will be appreciated that the term includes all plasmonic nanoparticles of various shapes that gives rise to a surface plasmon absorption and scattering spectrum [0097] As used herein, a "shape-directing agent" is a surfactant or reagent used to grow nanoparticles into specific morphologies. By utilizing specific shape-directing agents, specific morphologies may be selected, allowing for the optical properties of the resultant nanoparticles to be tuned. Exemplary shape-directing agents may include, but are not limited to, AgNO3, CTAB, CTAC, and other such agents known in the art. [0098] As used herein, "anisotropic" describes a material wherein a given property of said material depends on the direction in which it is measured. Moreover, something that is "anisotropic" changes in size or in its physical properties according to the direction in which it is measured. Examples of anisotropic materials may comprise graphite, carbon fiber, nanoparticles, etc. [0099] As used herein, "isotropic" describes a material wherein a given property of said material does not depend on the direction in which it is measured. Moreover, something that is "isotropic" remains constant in size or in its physical properties according to the direction in which it is measured. [00100] As used herein, "surface energy" may refer to the excess energy (i.e., the difference in the energy between a nanoparticle and the same number of atoms in an infinitely extended solid). More broadly, the surface energy of a particle may define its stability given its morphology and directly relates to the thermodynamics of a given nanoparticle. [00101] As used herein, "surface plasmon resonance (SPR)" refers to a phenomenon wherein the conduction electrons in the surface layer of a metal may become excited by photons of incident light with a certain angle of incidence, causing the excited conduction electrons to then propagate parallel to the metal surface in resonant oscillations (Zeng et al., 2017). With a constant light source wavelength and a thin metal surface layer, the certain angle that triggers SPR is dependent on the refractive index of the material near the metal surface. As used herein, "localized surface plasmon resonance (LSPR)" refers to an optical phenomena generated by light when it interacts with conductive nanoparticles that are smaller than the incident wavelength. As in surface plasmon resonance, the electric field of incident light can be deposited to collectively excite electrons of a conduction band, with the result being coherent localized plasmon oscillations with a resonant frequency that strongly depends on the composition, size, geometry, dielectric environment and separation distance of NP’s. [00102] As used herein, a "localized surface plasmon resonance (LSPR) peak" refers to the frequency or wavelength of incident light that exhibits the maximum or the highest spectral value of localized surface plasmon resonance. With regards to LSPR peaks, there are frequently two distinct peaks observed: a "longitudinal peak" and a "transverse peak". The former relates to the shape of the nanoparticle utilized, whereas the latter is a result of the innate properties of the material used. Gold, for instance, has an inherent transverse peak around 530nm, though the longitudinal peak of a gold NP can be tuned by adjusting its morphology. [00103] As used herein, "plasmonic light blocker" refers to a material with the ability to absorb, scatter, and/or extinguish incident light within a given region of the electromagnetic spectrum due to surface plasmonic resonance (SPR) or localized surface plasmonic resonance (LSPR), wherein the wavelength or range of wavelengths blocked correspond to the wavelength of incident light that induces the SPR or LSPR. Thus, the term "plasmonic light blocker” encompasses particles that absorb, scatter, and/or extinguish incident light within a given region of the electromagnetic spectrum due to SPR or LSPR. The particles can be incorporated in varying quantities within an optically transparent substrate to achieve an optically transparent material which exhibits a desired level of light filtering at one or more wavelengths or a range of wavelengths within the electromagnetic spectrum. The percent blocking at a particular wavelength can be determined from the material's transmission spectrum, where blocking=100−percent transmission (% T). [00104] “Tuning” as used herein refers to changing the size, shape, surface chemistry or aggregation state of a nanoparticle in order to optimize the optical and electronic properties of the nanoparticle to a particular application. The plasmonic peak can be tuned to any wavelength by a suitable design of the nanoparticles as discussed in U.S. Pat. No. 9,005,890, herein incorporated in its entirety by reference. [00105] Unless otherwise indicated, numeric ranges, for instance as in “from 2 to 10,” are inclusive of the numbers defining the range (e.g., 2 and 10). [00106] The term “biocompatible”, as used herein is intended to describe materials that do not elicit a substantial detrimental response in vivo. In certain embodiments, the materials are “biocompatible” if they are not toxic to cells. In certain embodiments, materials are “biocompatible” if their addition to cells in vitro results in less than or equal to 20% cell death, and/or their administration in vivo does not induce inflammation or other such adverse effects. [00107] The term “static concentration”, as used herein, refers to a concentration of the trigger, which may vary from about 1% to about 10%. For example, the static concentration may vary by +/−10%, +/−5%, +/−2%, or +/−1%. [00108] Unless otherwise indicated, ratios, percentages, parts, and the like are by weight. [00109] Unless otherwise indicated, numeric ranges, for instance as in “from 2 to 10,” are inclusive of the numbers defining the range (e.g., 2 and 10).

Accordingly, also provided are optical lenses (e.g., eyeglass lenses, camera lenses, contact lenses, etc.), ophthalmic devices (e.g., contact lenses, corneal onlays, corneal inlays, intraocular lenses, overlay lenses, etc.), screen covers (e.g., a transparent sheet configured to cover a computer monitor, tablet screen, or cell phone screen), and housings for electronic devices having LED displays which are formed at whole or in part from the optically transparent materials described herein. [00112] A variety of ophthalmic devices containing the nanoparticles described herein may be prepared, including hard contact lenses, soft contact lenses, corneal onlays, corneal inlays, intraocular lenses, or overlay lenses. Preferably, the ophthalmic device is a soft contact lens, which may be made from conventional or silicone hydrogel formulations.

[00199] The reactive monomer mixture may comprise both an acyclic polyamide and a cyclic polyamide or copolymers thereof. The acyclic polyamide can be any of those acyclic polyamides described herein or copolymers thereof, and the cyclic polyamide can be any of those cyclic polyamides described herein or copolymers thereof. The polyamide may be selected from the group polyvinylpyrrolidone (PVP), polyvinylmethylacetamide (PVMA), polydimethylacrylamide (PDMA), polyvinylacetamide (PNVA), poly hydroxyethyl (meth)acrylamide, polyacrylamide, and copolymers and mixtures thereof. [00200] The total amount of all polyamides in the reactive mixture may be in the range of between 1 weight percent and about 35 weight percent, including in the range of about 1 weight percent to about 15 weight percent, and in the range of about 5 weight percent to about 15 weight percent, in all cases, based on the total weight of the reactive components of the reactive monomer mixture. [00201] Without intending to be bound by theory, when used with a silicone hydrogel, the polyamide functions as an internal wetting agent. The polyamides may be non- polymerizable, and in this case, are incorporated into the silicone hydrogels as semi- interpenetrating networks. The polyamides are entrapped or physically retained within the silicone hydrogels. Alternatively, the polyamides may be polymerizable, for example as polyamide macromers or prepolymers, and in this case, are covalently incorporated into the silicone hydrogels. Mixtures of polymerizable and non-polymerizable polyamides may also be used. [00202] When the polyamides are incorporated into the reactive monomer mixture they may have a weight average molecular weight of at least 100,000 daltons; greater than about 150,000; between about 150,000 to about 2,000,000 daltons; between about 300,000 to about 1,800,000 daltons. Higher molecular weight polyamides may be used if they are compatible with the reactive monomer mixture. [00203] Cross-linking Agents [00204] It is generally desirable to add one or more cross-linking agents, also referred to as cross-linking monomers, multi-functional macromers, and prepolymers, to the reactive mixture. The cross-linking agents may be selected from bifunctional crosslinkers, trifunctional crosslinkers, tetrafunctional crosslinkers, and mixtures thereof, including silicone-containing and non-silicone containing cross-linking agents. Non-silicone-containing cross-linking agents include ethylene glycol dimethacrylate (EGDMA), tetraethylene glycol dimethacrylate (TEGDMA), trimethylolpropane trimethacrylate (TMPTMA), triallyl cyanurate (TAC), glycerol trimethacrylate, methacryloxyethyl vinylcarbonate (HEMAVc), allyl methacrylate, methylene bisacrylamide (MBA), and polyethylene glycol dimethacrylate wherein the polyethylene glycol has a molecular weight up to about 5000 Daltons. The cross-linking agents are used in the usual amounts, e.g., from about 0.000415 to about 0.0156 mole per 100 grams of reactive Formulas in the reactive mixture. Alternatively, if the hydrophilic monomers and/or the silicone-containing components are multifunctional by molecular design or because of impurities, the addition of a cross-linking agent to the reactive mixture is optional. Examples of hydrophilic monomers and macromers which can act as the cross-linking agents and when present do not require the addition of an additional cross-linking agent to the reactive mixture include (meth)acrylate and (meth)acrylamide endcapped polyethers. Other cross-linking agents will be known to one skilled in the art and may be used to make the silicone hydrogel of the present invention. [00205] It may be desirable to select crosslinking agents with similar reactivity to one or more of the other reactive components in the formulation. In some cases, it may be desirable to select a mixture of crosslinking agents with different reactivity in order to control some physical, mechanical or biological property of the resulting silicone hydrogel. The structure and morphology of the silicone hydrogel may also be influenced by the diluent(s) and cure conditions used. [00206] Multifunctional silicone-containing components, including macromers, cross- linking agents, and prepolymers, may also be included to further increase the modulus and retain tensile strength. The silicone containing cross-linking agents may be used alone or in combination with other cross-linking agents. An example of a silicone containing component which can act as a cross-linking agent and, when present, does not require the addition of a crosslinking monomer to the reactive mixture includes α, ω-bismethacryloxypropyl polydimethylsiloxane. [00207] Cross-linking agents that have rigid chemical structures and polymerizable groups that undergo free radical polymerization may also be used. Non-limiting examples of suitable rigid structures include cross-linking agents comprising phenyl and benzyl moieties, such are 1,4-phenylene diacrylate, 1,4-phenylene dimethacrylate, 2,2-bis(4- methacryloxyphenyl)-propane, 2,2-bis[4-(2-acryloxyethoxy)phenyl]propane, 2,2-bis[4-(2- hydroxy-3-methacryloxypropoxy)-phenyl]propane, and 4-vinylbenzyl methacrylate, and combinations thereof. Rigid crosslinking agents may be included in amounts between about 0.5 and about 15, or 2-10, 3-7 based upon the total weight of all of the reactive components. The physical and mechanical properties of the silicone hydrogels of the present invention may be optimized for a particular use by adjusting the components in the reactive mixture. [00208] Non-limiting examples of silicone cross-linking agents also include the multi- functional silicone-containing components described above, such as compounds of Formula E (and its sub-formulae) and the multi-functional compounds shown in the tables above.

[00265] The phenomena of thermal reshaping of anisotropic nanoparticles has been established (Kennedy, et al, ACS Appl. Mater. Interfaces, 2018; Cho, et al., J. Phys. Chem. C, 2020; Mohamed, et al., J. Phys. Chem. B, 1998). The melting point of materials has been shown to drop significantly in the nano range due to the increased proportion of high-energy surface atoms. Elevated temperatures have thus been shown to cause surface diffusion of Au atoms and rearrangement to more thermodynamically stable conformations (Kennedy, et al, ACS Appl. Mater. Interfaces, 2018; Huang, et al., RSC Adv., 2014). This process has led to a decrease in aspect ratio and a gradual transition to a more spherical morphology. For gold nanorods, thermal stability has been shown to decrease with increasing aspect ratio, likely due to curvature-induced surface diffusion of atoms at the ends of the rod (Taylor, et al., ACS Nano, 2014). Due to the dependence of Localized-Surface Plasmon Resonance (LSPR) on nanoparticle shape, minimization of nanoparticle reshaping at elevated temperatures has been noted as being of importance. [00266] The effect of poly(vinylpyrrolidone)’s (PVP’s) molecular weight on the thermal reshaping of gold bipyramids integrated into contact lenses was tested. Bipyramids were coated with 55 kDa (FIG. 1A), 360 kDa (FIG. 1B), or 1300 kDa PVP (FIG. 1C) and cured in an Etafilcon mixture to produce contact lenses. The lenses were added to MilliQ water and autoclaved at 121°C for 30 min. Ultraviolet-Visible (UV-Vis) spectroscopy was performed before and after autoclaving to assess the effect on bipyramid thermal reshaping. FIGS. 1A-1C show that increases in the molecular weight of PVP decreased blue-shifting of the autoclaved nanoparticles. For the molecular weights tested, the longitudinal LSPR peak blue-shifted 60 nm (55 kDa, FIG. 1A), 56 nm (360 kDa, FIG. 1B), and 26 nm (1300 kDa, FIG. 1C) after autoclaving, respectively. [00267] The effects of autoclaving on colloidal stability and reshaping for gold nanorods were examined, as shown in FIGS. 2A-2C. Three colloidal suspensions of nanorods of different sizes/aspect ratios were synthesized and then coated with cetyltrimethylammonium bromide (CTAB) (FIG. 2A), 55 kDa (FIG. 2B), or 1300 kDa (FIG. 2C) PVP. Solutions were autoclaved, and the absorbance spectra were used to determine the extent of reshaping. As- synthesized nanorods coated with CTAB (FIG. 2A) all reverted to a single LSPR peak post- autoclave, indicating a spherical shape. The low-molecular weight (55 kDa) PVP-coated nanorods (FIG. 2B) all fell out of solution and thus presented very weak and broad LSPR peaks. By contrast, the high-molecular weight (1300 kDa) PVP-coated nanorods retained both LSPR peaks and showed only minor blue-shifting, as shown in FIG. 2C.
