[0259] In some embodiments, the ordinary skilled worker, considering the therapeutic context, age, and general health of the recipient, will be able to devise an appropriate dosage level and dosing regimen using the pharmaceutical compositions described herein for treatment of various conditions in various patients. For example, in some embodiments, a selected dosage depends upon the desired therapeutic effect, on the route of administration, and on the duration of the treatment desired. In some embodiments, generally dosage levels of about 0.001 mg to about 5 mg of nucleic acid per kg of body weight are administered each dosage to mammals. More specifically, in some embodiments, a preferential dose for nucleic acids within the disclosed nanoparticles is about 0.1 mg / kg to about 1.0 mg/kg. For the disclosed nanoparticles, generally dosage levels of about 0.2 mg to about 100 mg of four components (ionizable lipid, cholesterol, conjugate-linker conjugate, and phospholipid) / kg of body weight are administered to mammals. More specifically, in some embodiments, a preferential dose of the disclosed nanoparticles is about 0.5 mg / kg to about 5 mg / kg of the four components / kg of body weight. [0260] In some embodiments, a pharmaceutical composition described herein is administered locally, for example by injection directly into a site to be treated. Typically, the injection causes an increased localized concentration of the composition which is greater than that which can be achieved by systemic administration. In some embodiments, a pharmaceutical composition described herein can be combined with a matrix as described herein to assist in creating an increased localized concentration of the polypeptide compositions by reducing the passive diffusion of the polypeptides out of the site to be treated. A. Preparations for parenteral administration [0261] In some embodiments, the compositions, preparations, nanoparticles, and/or nanomaterials disclosed herein, including those containing lipid nanoparticles, are administered in an aqueous solution, by parenteral injection.

In some embodiments, a peptide is dispersed or suspended in a core, which may be liquid or solid in nature, of any of the described compositions, preparations, nanoparticles, and/or nanomaterials. Unless specifically defined herein, microparticles, microspheres, and microcapsules are used interchangeably. In some embodiments, a polymer may be cast as a thin slab or film, ranging from nanometers to four centimeters, a powder produced by grinding or other standard techniques, or even a gel such as a hydrogel. [0263] In some embodiments, non-biodegradable matrices are used for delivery of the described compositions, preparations, nanoparticles, and/or nanomaterials. In some embodiments, biodegradable matrices are used for delivery of the described compositions, preparations, nanoparticles, and/or nanomaterials. In some embodiments, biodegradable matrices are preferred. In some embodiments, biodegradable matrices comprise natural or synthetic polymers. In some embodiments, synthetic polymers are preferred due to the better characterization of degradation and release profiles. In some embodiments, a polymer is selected based on the period over which release is desired. In some embodiments, linear release may be most useful, although in others a pulse release or “bulk release” may provide more effective results. In some embodiments, a polymer may be in the form of a hydrogel (typically in absorbing up to about 90% by weight of water), and can optionally be crosslinked with multivalent ions or polymers. [0264] The matrices can be formed by solvent evaporation, spray drying, solvent extraction and other methods known to those skilled in the art. Bioerodible microspheres can be prepared using any of the methods developed for making microspheres for drug delivery, for example, as described by Mathiowitz and Langer, J. Controlled Release, 5:13-22 (1987); Mathiowitz, et al., Reactive Polymers, 6:275-283 (1987); and Mathiowitz, et al., J. Appl. Polymer Sci., 35:755-774 (1988), the disclosure of which is hereby incorporated by reference in its entirety herein. [0265] In some embodiments, the described compositions, preparations, nanoparticles, and/or nanomaterials can be formulated for local release to treat the area of implantation or injection – which will typically deliver a dosage that is much less than the dosage for treatment of an entire body – or systemic delivery. These can be implanted or injected subcutaneously, into the muscle, fat, or swallowed. C.

[0271] As used herein, an “RNA-guided DNA binding agent” means a polypeptide or complex of polypeptides having RNA and DNA binding activity, or a DNA-binding subunit of such a complex, wherein the DNA binding activity is sequence-specific and depends on the sequence of the RNA. Exemplary RNA-guided DNA binding agents include Cas cleavases/nickases and inactivated forms thereof (“dCas DNA binding agents”). “Cas nuclease”, as used herein, encompasses Cas cleavases, Cas nickases, and dCas DNA binding agents. Cas cleavases/nickases and dCas DNA binding agents include a Csm or Cmr complex of a type III CRISPR system, the CaslO, Csml, or Cmr2 subunit thereof, a Cascade complex of a type I CRISPR system, the Cas3 subunit thereof, and Class 2 Cas nucleases. As used herein, a “Class 2 Cas nuclease” is a single chain polypeptide with RNA-guided DNA binding activity. Class 2 Cas nucleases include Class 2 Cas cleavases/nickases (e.g., H840A, D10A, or N863 A variants), which further have RNA-guided DNA cleavases or nickase activity, and Class 2 dCas DNA binding agents, in which cleavase/nickase activity is inactivated. Class 2 Cas nucleases include, for example, Cas9, Cpfl, C2cl, C2c2, C2c3, HF Cas9 (e.g., N497A, R661A, Q695A, Q926A variants), HypaCas9 (e.g., N692A, M694A, Q695A, H698A variants), eSPCas9(1.0) (e.g., K810A, K1003A, R1060A variants), and eSPCas9(1.1) (e.g., K848A, K1003A, R1060A variants) proteins and modifications thereof. Cpfl protein, Zetsche et al., Cell, 163: 1-13 (2015), is homologous to Cas9, and contains a RuvC-like nuclease domain. Cpfl sequences of Zetsche are incorporated by reference in their entirety herein. See, e.g., Zetsche, Tables Sl and S3. See, e.g, Makarova et al., Nat Rev Microbiol, 13(11): 722-36 (2015); Shmakov et al., Molecular Cell, 60:385-397 (2015), the contents of which are hereby incorporated in its entirety herein. [0272] As used herein, “ribonucleoprotein” (RNP) or “RNP complex” refers to a guide RNA together with an RNA-guided DNA binding agent, such as a Cas nuclease, e.g., a Cas cleavase, Cas nickase, or dCas DNA binding agent (e.g., Cas9). In some embodiments, the guide RNA guides the RNA-guided DNA binding agent such as Cas9 to a target sequence, and the guide RNA hybridizes with and the agent binds to the target sequence; in cases where the agent is a cleavase or nickase, binding can be followed by cleaving or nicking. [0273] In some embodiments, cargo for a LNP composition includes at least one guide RNA comprising guide sequences that direct an RNA-guided DNA binding agent, which can be a nuclease (e.g., a Cas nuclease such as Cas9), to a target DNA. gRNA may guide the Cas nuclease or Class 2 Cas nuclease to a target sequence on a target nucleic acid molecule. In some embodiments, a gRNA binds with and provides specificity of cleavage by a Class 2 Cas nuclease. In some embodiments, a gRNA and a Cas nuclease may form a ribonucleoprotein (RNP), e.g., a CRISPR/Cas complex such as a CRISPR/Cas9 complex. In some embodiments, a CRISPR/Cas complex may be a Type-II CRISPR/Cas9 complex. In some embodiments, a CRISPR/Cas complex may be a Type-V CRISPR/Cas complex, such as a Cpfl/guide RNA complex. Cas nucleases and cognate gRNAs may be paired. A gRNA scaffold structures that pair with each Class 2 Cas nuclease vary with the specific CRISPR/Cas system. [0274] “Guide RNA” , “gRNA”, and simply “guide” are used herein interchangeably to refer to either a crRNA (also known as CRISPR RNA), or the combination of a crRNA and a trRNA (also known as tracrRNA). Guide RNAs can include modified RNAs as described herein. The crRNA and trRNA may be associated as a single RNA molecule (single guide RNA, sgRNA) or in two separate RNA molecules (dual guide RNA, dgRNA). “Guide RNA” or “gRNA” refers to each type. trRNA may be a naturally-occurring sequence, or a trRNA sequence with modifications or variations compared to naturally-occurring sequences. [0275] As used herein, a “guide sequence” refers to a sequence within a guide RNA that is complementary to a target sequence and functions to direct a guide RNA to a target sequence for binding or modification ( e.g., cleavage) by an RNA-guided DNA binding agent. A “guide sequence” may also be referred to as a “targeting sequence,” or a “spacer sequence.” A guide sequence can be 20 base pairs in length, e.g., in the case of Streptococcus pyogenes (i.e., Spy Cas9) and related Cas9 homologs/orthologs. Shorter or longer sequences can also be used as guides, e.g., 15-, 16-, 17-, 18-, 19-, 21-, 22-, 23-, 24-, or 25-nucleotides in length. In some embodiments, a target sequence is in a gene or on a chromosome, for example, and is complementary to a guide sequence. In some embodiments, a degree of complementarity or identity between a guide sequence and its corresponding target sequence may be about or at least 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, a guide sequence and the target region may be 100% complementary or identical over a region of at least 15, 16, 17, 18, 19, or 20 contiguous nucleotides. In other embodiments, a guide sequence and a target region may contain at least one mismatch. For example, a guide sequence and a target sequence may contain 1, 2, 3, or 4 mismatches, where the total length of the target sequence is at least 17, 18, 19, 20 or more base pairs. In some embodiments, a guide sequence and a target region may contain 1-4 mismatches where a guide sequence comprises at least 17, 18, 19, 20 or more nucleotides. In some embodiments, a guide sequence and the target region may contain 1, 2, 3, or 4 mismatches where the guide sequence comprises 20 nucleotides. [0276] Target sequences for RNA-guided DNA binding proteins such as Cas proteins include both the positive and negative strands of genomic DNA (i.e., the sequence given and the sequence’s reverse compliment), as a nucleic acid substrate for a Cas protein is a double stranded nucleic acid. Accordingly, where a guide sequence is said to be “complementary to a target sequence”, it is to be understood that the guide sequence may direct a guide RNA to bind to the reverse complement of a target sequence. Thus, in some embodiments, where the guide sequence binds the reverse complement of a target sequence, the guide sequence is identical to certain nucleotides of the target sequence (e.g., the target sequence not including the PAM) except for the substitution of U for T in the guide sequence. [0277] The length of the targeting sequence may depend on the CRISPR/Cas system and components used. For example, different Class 2 Cas nucleases from different bacterial species have varying optimal targeting sequence lengths. Accordingly, the targeting sequence may comprise 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 35, 40, 45, 50, or more than 50 nucleotides in length. In some embodiments, the targeting sequence length is 0, 1, 2, 3, 4, or 5 nucleotides longer or shorter than the guide sequence of a naturally-occurring nucleotide sequence. [0278] CRISPR/Cas system. In certain embodiments, a Cas nuclease and gRNA scaffold will be derived from the same CRISPR/Cas system. In some embodiments, a targeting sequence may comprise or consist of 18-24 nucleotides. In some embodiments, a targeting sequence may comprise or consist of 19-21 nucleotides. In some embodiments, the targeting sequence may comprise or consist of 20 nucleotides. [0279] In some embodiments, a sgRNA is a “Cas9 sgRNA” capable of mediating RNA-guided DNA cleavage by a Cas9 protein. In some embodiments, a sgRNA is a “Cpfl sgRNA” capable of mediating RNA-guided DNA cleavage by a Cpfl protein. In some embodiments, a gRNA comprises a crRNA and tracr RNA sufficient for forming an active complex with a Cas9 protein and mediating RNA-guided DNA cleavage. In some embodiments, a gRNA comprises a crRNA sufficient for forming an active complex with a Cpfl protein and mediating RNA-guided DNA cleavage. See Zetsche 2015. [0280] Certain embodiments of the invention also provide nucleic acids, e.g., expression cassettes, encoding the gRNA described herein. A “guide RNA nucleic acid” is used herein to refer to a guide RNA (e.g. an sgRNA or a dgRNA) and a guide RNA expression cassette, which is a nucleic acid that encodes one or more guide RNAs. [0281] Certain embodiments of the present disclosure also provide delivery of adenine base editors (“ABEs”) using the LNPs compositions, preparations, nanoparticles, and/or nanomaterials described herein. ABEs and methods of their use are described, e.g. in U.S. Patent No.10,113,163 and U.S. Patent Publication No. 2021/0130805, the contents of each of which are hereby incorporated by reference in their entireties. [0282] Certain embodiments of the present disclosure also provide delivery of cytosine base editors (“CBEs”) using the LNPs compositions, preparations, nanoparticles, and/or nanomaterials described herein. ABEs and methods of their use are described, e.g. in U.S. Patent Nos.10,167,457 and 9,840,699, the contents of each of which are hereby incorporated by reference in their entireties. [0283] The term “base editor (BE),” or “nucleobase editor (NBE)” refers to an agent comprising a polypeptide that is capable of making a modification to a base (e.g., A, T, C, G, or U) within a nucleic acid sequence (e.g., DNA or RNA). In some embodiments, the base editor is capable of deaminating a base within a nucleic acid. In some embodiments, the base editor is capable of deaminating a base within a DNA molecule. In some embodiments, the base editor is capable of deaminating an adenine (A) in DNA. . In some embodiments, the deaminase is a cytosine deaminase or a cytidine deaminase. In some embodiments, the base editor is a fusion protein comprising a nucleic acid programmable DNA binding protein (napDNAbp) fused to an adenosine deaminase. In some embodiments, the base editor is a Cas9 protein fused to an adenosine deaminase. In some embodiments, the base editor is a Cas9 nickase (nCas9) fused to an adenosine deaminase. In some embodiments, the base editor is a nuclease-inactive Cas9 (dCas9) fused to an adenosine deaminase. In some embodiments, the base editor is fused to an inhibitor of base excision repair, for example, a UGI domain, or a dISN domain. In some embodiments, the fusion protein comprises a Cas9 nickase fused to a deaminase and an inhibitor of base excision repair, such as a UGI or dISN domain. The term “nucleic acid programmable DNA binding protein” or “napDNAbp” refers to a protein that associates with a nucleic acid (e.g., DNA or RNA), such as a guide nuclic acid, that guides the napDNAbp to a specific nucleic acid sequence. For example, a Cas9 protein can associate with a guide RNA that guides the Cas9 protein to a specific DNA sequence that has complementary to the guide RNA. In some embodiments, the napDNAbp is a class 2 microbial CRISPR-Cas effector. In some embodiments, the napDNAbp is a Cas9 domain, for example a nuclease active Cas9, a Cas9 nickase (nCas9), or a nuclease inactive Cas9 (dCas9). Examples of nucleic acid programmable DNA binding proteins include, without limitation, Cas9 (e.g., dCas9 and nCas9), CasX, CasY, Cpf1, C2c1, C2c2, C2C3, and Argonaute. It should be appreciated, however, that nucleic acid programmable DNA binding proteins also include nucleic acid programmable proteins that bind RNA. For example, the napDNAbp may be associated with a nucleic acid that guides the napDNAbp to an RNA. Other nucleic acid programmable DNA binding proteins are also within the scope of this disclosure, though they may not be specifically listed in this disclosure. F. Modified RNAs [0284] In certain embodiments, the disclosed compositions, preparations, nanoparticles, and/or nanomaterials comprise modified nucleic acids, including modified RNAs. [0285] Modified nucleosides or nucleotides can be present in an RNA, for example a gRNA or mRNA. A gRNA or mRNA comprising one or more modified nucleosides or nucleotides, for example, is called a “modified” RNA to describe the presence of one or more non-naturally and/or naturally occurring components or configurations that are used instead of or in addition to the canonical A, G, C, and U residues. In some embodiments, a modified RNA is synthesized with a non-canonical nucleoside or nucleotide, here called “modified.” [0286] Modified nucleosides and nucleotides can include one or more of: (i) alteration, e.g., replacement, of one or both of the non-linking phosphate oxygens and/or of one or more of the linking phosphate oxygens in the phosphodiester backbone linkage (an exemplary backbone modification); (ii) alteration, e.g., replacement, of a constituent of the ribose sugar, e.g. , of the 2' hydroxyl on the ribose sugar (an exemplary sugar modification); (iii) wholesale replacement of the phosphate moiety with “dephospho” linkers (an exemplary backbone modification); (iv) modification or replacement of a naturally occurring nucleobase, including with a non-canonical nucleobase (an exemplary base modification); (v) replacement or modification of the ribose- phosphate backbone (an exemplary backbone modification); (vi) modification of the 3' end or 5' end of the oligonucleotide, e.g. , removal, modification or replacement of a terminal phosphate group or conjugation of a moiety, cap or linker (such 3' or 5' cap modifications may comprise a sugar and/or backbone modification); and (vii) modification or replacement of the sugar (an exemplary sugar modification). Certain embodiments comprise a 5' end modification to an mRNA, gRNA, or nucleic acid. Certain embodiments comprise a 3' end modification to an mRNA, gRNA, or nucleic acid. A modified RNA can contain 5' end and 3' end modifications. A modified RNA can contain one or more modified residues at non-terminal locations. In certain embodiments, a gRNA includes at least one modified residue. In certain embodiments, an mRNA includes at least one modified residue. [0287] Unmodified nucleic acids can be prone to degradation by, e.g., intracellular nucleases or those found in serum. For example, nucleases can hydrolyze nucleic acid phosphodiester bonds. Accordingly, in one aspect the RNAs (e.g. mRNAs, gRNAs) described herein can contain one or more modified nucleosides or nucleotides, e.g., to introduce stability toward intracellular or serum- based nucleases. In some embodiments, the modified gRNA molecules described herein can exhibit a reduced innate immune response when introduced into a population of cells, both in vivo and ex vivo. The term “innate immune response” includes a cellular response to exogenous nucleic acids, including single stranded nucleic acids, which involves the induction of cytokine expression and release, particularly the interferons, and cell death. [0288] Accordingly, in some embodiments, RNA or nucleic acids in the disclosed the disclosed compositions, preparations, nanoparticles, and/or nanomaterials comprise at least one modification which confers increased or enhanced stability to the nucleic acid, including, for example, improved resistance to nuclease digestion in vivo. As used herein, the terms “modification” and “modified” as such terms relate to the nucleic acids provided herein, include at least one alteration which preferably enhances stability and renders the RNA or nucleic acid more stable (e.g., resistant to nuclease digestion) than the wild-type or naturally occurring version of the RNA or nucleic acid. As used herein, the terms “stable” and “stability” as such terms relate to the nucleic acids of the present invention, and particularly with respect to the RNA, refer to increased or enhanced resistance to degradation by, for example nucleases (i.e., endonucleases or exonucleases) which are normally capable of degrading such RNA. Increased stability can include, for example, less sensitivity to hydrolysis or other destruction by endogenous enzymes (e.g., endonucleases or exonucleases) or conditions within the target cell or tissue, thereby increasing or enhancing the residence of such RNA in the target cell, tissue, subject and/or cytoplasm. The stabilized RNA molecules provided herein demonstrate longer half-lives relative to their naturally occurring, unmodified counterparts (e.g. the wild-type version of the mRNA). Also contemplated by the terms “modification” and “modified” as such terms related to the mRNA of the LNP compositions disclosed herein are alterations which improve or enhance translation of mRNA nucleic acids, including for example, the inclusion of sequences which function in the initiation of protein translation (e.g., the Kozac consensus sequence). (Kozak, M., Nucleic Acids Res 15 (20): 8125- 48 (1987), the contents of which are hereby incorporated by reference herein in its entirety). [0289] In some embodiments, an RNA or nucleic acid of the disclosed compositions, preparations, nanoparticles, and/or nanomaterials disclosed herein have undergone a chemical or biological modification to render it more stable. Exemplary modifications to an RNA include the depletion of a base (e.g., by deletion or by the substitution of one nucleotide for another) or modification of a base, for example, the chemical modification of a base. The phrase “chemical modifications” as used herein, includes modifications which introduce chemistries which differ from those seen in naturally occurring RNA, for example, covalent modifications such as the introduction of modified nucleotides, (e.g., nucleotide analogs, or the inclusion of pendant groups which are not naturally found in such RNA molecules). [0290] In some embodiments of a backbone modification, the phosphate group of a modified residue can be modified by replacing one or more of the oxygens with a different substituent. Further, the modified residue, e.g., modified residue present in a modified nucleic acid, can include the wholesale replacement of an unmodified phosphate moiety with a modified phosphate group as described herein. In some embodiments, the backbone modification of the phosphate backbone can include alterations that result in either an uncharged linker or a charged linker with unsymmetrical charge distribution. Examples of modified phosphate groups include, phosphorothioate, phosphoroselenates, borano phosphates, borano phosphate esters, hydrogen phosphonates, phosphoroamidates, alkyl or aryl phosphonates and phosphotriesters. The phosphorous atom in an unmodified phosphate group is achiral. However, replacement of one of the non-bridging oxygens with one of the above atoms or groups of atoms can render the phosphorous atom chiral. The stereogenic phosphorous atom can possess either the “R” configuration (herein Rp) or the “S” configuration (herein Sp). The backbone can also be modified by replacement of a bridging oxygen, (i.e., the oxygen that links the phosphate to the nucleoside), with nitrogen (bridged phosphoroamidates), sulfur (bridged phosphorothioates) and carbon (bridged methylenephosphonates). The replacement can occur at either linking oxygen or at both of the linking oxygens. The phosphate group can be replaced by non-phosphorus containing connectors in certain backbone modifications. In some embodiments, the charged phosphate group can be replaced by a neutral moiety. Examples of moieties which can replace the phosphate group can include, without limitation, e.g., methyl phosphonate, hydroxylamino, siloxane, carbonate, carboxymethyl, carbamate, amide, thioether, ethylene oxide linker, sulfonate, sulfonamide, thioformacetal, formacetal, oxime, methyleneimino, methylenemethylimino, methylenehydrazo, methylenedimethylhydrazo and methyleneoxymethylimino. G. mRNA [0291] In some embodiments, the disclosed compositions, preparations, nanoparticles, and/or nanomaterials comprise an mRNA comprising an open reading frame (ORF) encoding an RNA- guided DNA binding agent, such as a Cas nuclease, or Class 2 Cas nuclease as described herein. In some embodiments, an mRNA comprising an ORF encoding an RNA-guided DNA binding agent, such as a Cas nuclease or Class 2 Cas nuclease, is provided, used, or administered. An mRNA may comprise one or more of a 5' cap, a 5' untranslated region (UTR), a 3' UTRs, and a polyadenine tail. The mRNA may comprise a modified open reading frame, for example to encode a nuclear localization sequence or to use alternate codons to encode the protein. [0292] mRNA in the disclosed compositions, preparations, nanoparticles, and/or nanomaterials may encode, for example, a secreted hormone, enzyme, receptor, polypeptide, peptide or other protein of interest that is normally secreted. In one embodiment of the invention, the mRNA may optionally have chemical or biological modifications which, for example, improve the stability and/or half-life of such mRNA or which improve or otherwise facilitate protein production. [0293] In addition, suitable modifications include alterations in one or more nucleotides of a codon such that the codon encodes the same amino acid but is more stable than the codon found in the wild-type version of the mRNA. For example, an inverse relationship between the stability of RNA and a higher number cyti dines (C's) and/or uridines (U's) residues has been demonstrated, and RNA devoid of C and U residues have been found to be stable to most RNases (Heidenreich, et al. J Biol Chem 269, 2131-8 (1994), the disclosure of which is hereby incorporated by reference herein in its entirety). In some embodiments, the number of C and/or U residues in an mRNA sequence is reduced. In another embodiment, the number of C and/or U residues is reduced by substitution of one codon encoding a particular amino acid for another codon encoding the same or a related amino acid. Contemplated modifications to the mRNA nucleic acids of the present invention also include the incorporation of pseudouridines. The incorporation of pseudouridines into the mRNA nucleic acids of the present invention may enhance stability and translational capacity, as well as diminishing immunogenicity in vivo. See, e.g., Kariko, K., et al., Molecular Therapy 16 (11): 1833-1840 (2008), the contents of which is hereby incorporated by reference herein in its entirety. Substitutions and modifications to the mRNA of the present invention may be performed by methods readily known to one or ordinary skill in the art. [0294] The constraints on reducing the number of C and U residues in a sequence will likely be greater within the coding region of an mRNA, compared to an untranslated region, (i.e., it will likely not be possible to eliminate all of the C and U residues present in the message while still retaining the ability of the message to encode the desired amino acid sequence). The degeneracy of the genetic code, however presents an opportunity to allow the number of C and/or U residues that are present in the sequence to be reduced, while maintaining the same coding capacity (i.e., depending on which amino acid is encoded by a codon, several different possibilities for modification of RNA sequences may be possible). [0295] The term modification also includes, for example, the incorporation of non-nucleotide linkages or modified nucleotides into the mRNA sequences of the present invention (e.g., modifications to one or both the 3' and 5' ends of an mRNA molecule encoding a functional secreted protein or enzyme). Such modifications include the addition of bases to an mRNA sequence (e.g., the inclusion of a poly A tail or a longer poly A tail), the alteration of the 3' UTR or the 5' UTR, complexing the mRNA with an agent (e.g., a protein or a complementary nucleic acid molecule), and inclusion of elements which change the structure of an mRNA molecule (e.g., which form secondary structures). [0296] The poly A tail is thought to stabilize natural messengers. Therefore, in one embodiment a long poly A tail can be added to an mRNA molecule thus rendering the mRNA more stable. Poly A tails can be added using a variety of art-recognized techniques. For example, long poly A tails can be added to synthetic or in vitro transcribed mRNA using poly A polymerase (Yokoe, et al. Nature Biotechnology. 1996; 14: 1252-1256, the contents of which is hereby incorporated by reference herein in its entirety). A transcription vector can also encode long poly A tails. In addition, poly A tails can be added by transcription directly from PCR products. In one embodiment, the length of the poly A tail is at least about 90, 200, 300, 400 at least 500 nucleotides. In one embodiment, the length of the poly A tail is adjusted to control the stability of a modified mRNA molecule of the invention and, thus, the transcription of protein. For example, since the length of the poly A tail can influence the half-life of an mRNA molecule, the length of the poly A tail can be adjusted to modify the level of resistance of the mRNA to nucleases and thereby control the time course of protein expression in a cell. In one embodiment, the stabilized mRNA molecules are sufficiently resistant to in vivo degradation (e.g., by nucleases), such that they may be delivered to the target cell without a transfer vehicle. [0297] In some embodiment embodiments, an mRNA can be modified by the incorporation 3' and/or 5' untranslated (UTR) sequences which are not naturally found in the wild-type mRNA. In one embodiment, 3' and/or 5' flanking sequence which naturally flanks an mRNA and encodes a second, unrelated protein can be incorporated into the nucleotide sequence of an mRNA molecule encoding a therapeutic or functional protein in order to modify it. For example, 3' or 5' sequences from mRNA molecules which are stable (e.g., globin, actin, GAPDH, tubulin, histone, or citric acid cycle enzymes) can be incorporated into the 3' and/or 5' region of a sense mRNA nucleic acid molecule to increase the stability of the sense mRNA molecule. See, e.g., US 2003/0083272, the contents of which is hereby incorporated by reference herein in its entirety. More detailed descriptions of the mRNA modifications can be found in US 2017/0210698A1, at pages 57-68, which content is incorporated herein by reference in its entirety. H. Template nucleic acid [0298] The compositions, preparations, nanoparticles, and/or nanomaterials and methods disclosed herein may include a template nucleic acid. A template may be used to alter or insert a nucleic acid sequence at or near a target site for an RNA-guided DNA binding protein such as a Cas nuclease, e.g., a Class 2 Cas nuclease. In some embodiments, the methods comprise introducing a template to the cell. In some embodiments, a single template may be provided. In some embodiments, two or more templates may be provided such that editing may occur at two or more target sites. For example, different templates may be provided to edit a single gene in a cell, or two different genes in a cell. [0299] In some embodiments, a template may be used in homologous recombination. In some embodiments, the homologous recombination may result in the integration of the template sequence or a portion of the template sequence into the target nucleic acid molecule. In some embodiments, a template may be used in homology-directed repair, which involves DNA strand invasion at the site of the cleavage in the nucleic acid. In some embodiments, homology-directed repair may result in including the template sequence in the edited target nucleic acid molecule. In some embodiments, a template may be used in gene editing mediated by non-homologous end joining. In some embodiments, a template sequence has no similarity to the nucleic acid sequence near the cleavage site. In some embodiments, a template or a portion of the template sequence is incorporated. In some embodiments, a template includes flanking inverted terminal repeat (ITR) sequences. [0300] In some embodiments, a template sequence may correspond to, comprise, or consist of an endogenous sequence of a target cell. It may also or alternatively correspond to, comprise, or consist of an exogenous sequence of a target cell. As used herein, the term “endogenous sequence” refers to a sequence that is native to the cell. The term “exogenous sequence” refers to a sequence that is not native to a cell, or a sequence whose native location in the genome of the cell is in a different location. In some embodiments, the endogenous sequence may be a genomic sequence of the cell. [0301] In some embodiments, the endogenous sequence may be a chromosomal or extrachromosomal sequence. In some embodiments, an endogenous sequence may be a plasmid sequence of the cell. [0302] In some embodiments, a template contains ssDNA or dsDNA containing flanking invert- terminal repeat (ITR) sequences. In some embodiments, a template is provided as a vector, plasmid, minicircle, nanocircle, or PCR product. [0303] In some embodiments, a nucleic acid is purified. In some embodiments, a nucleic acid is purified using a precipitation method (e.g., LiCl precipitation, alcohol precipitation, or an equivalent method, e.g., as described herein). In some embodiments, a nucleic acid is purified using a chromatography-based method, such as an HPLC-based method or an equivalent method (e.g., as described herein). In some embodiments, a nucleic acid is purified using both a precipitation method (e.g, LiCl precipitation) and an HPLC-based method. In some embodiments, the nucleic acid is purified by tangential flow filtration (TFF). IV. Methods of manufacturing LNPs [0304] Methods of manufacturing lipid nanoparticles are known in the art. In some embodiments, the described compositions, preparations, nanoparticles, and/or nanomaterials are manufactured using microfluidics. For instance, exemplary methods of using microfluidics to form lipid nanoparticles are described by Leung, A.K.K, et al., J Phys Chem, 116:18440-18450 (2012), Chen, D., et al., J Am Chem Soc, 134:6947-6951 (2012), and Belliveau, N.M., et al., Molecular Therapy- Nucleic Acids, 1: e37 (2012), the disclosures of which are hereby incorporated by reference in their entireties. [0305] Briefly, a cargo, such as a cargo described herein, is prepared in a first buffer solution. The other lipid nanoparticle components (such as ionizable lipid, conjugate-linker lipids, cholesterol, and phospholipid) are prepared in a second buffer solution. In some embodiments, a syringe pump introduces the two solutions into a microfluidic device. The two solutions come into contact within the microfluidic device to form lipid nanoparticles encapsulating the cargo. [0306] Methods of screening the disclosed lipid nanoparticles are described in International Patent Application No. PCT/US2018/058171, which is incorporated by reference in its entirety herein. In some embodiments, the screening methods characterize vehicle delivery preparations to identify preparations with a desired tropism and that deliver functional cargo to the cytoplasm of specific cells. In some embodiments, the screening method uses a reporter that has a functionality that can be detected when delivered to the cell. For example, detecting a functional reporter in a cell indicates that the LNP preparation delivers functional cargo to the cell. Among other things, in some embodiments, a chemical composition identifier is included in each different delivery vehicle formulation to keep track of the chemical composition specific for each different delivery vehicle formulation. In some embodiments, a chemical composition identifier is a nucleic acid barcode. In some embodiments, a sequence of the nucleic acid barcode is paired to which chemical components were used to formulate the LNP preparation in which it is loaded so that when the nucleic acid barcode is sequenced, the chemical composition of the delivery vehicle that delivered the barcode is identified. Representative barcodes include, but are not limited to, barcodes described by Sago, 2018 PNAS, Sago, JACS 2018, the disclosure of which is hereby incorporated by reference in its entirety. Representative reporters include, but are not limited to siRNA, mRNA, nuclease protein, nuclease mRNA, small molecules, epigenetic modifiers, and phenotypic modifiers. DNA (genomic and DNA barcodes) can be isolated using QuickExtract (Lucigen) and sequenced using Illumina MiniSeq as described by Sago et al. PNAS 2018, Sago et al. JACs 2018, Sago, Lokugamage et al. Nano Letters 2018, the disclosures of which are hereby incorporated by reference in their entireties). V. Methods of use [0307] Among other things, the present disclosure describes methods of using compositions, preparations, nanoparticles, and/or nanomaterials described herein. For example, in some embodiments, the present disclosure describes methods of using compositions, preparations, nanoparticles, and/or nanomaterials to deliver cargo to specific cells, tissues, or organs, as described herein. As another example, in some embodiments, the present disclosure describes methods of treatment and/or delaying and/or arresting progression of a disease or disorder using compositions, preparations, nanoparticles, and/or nanomaterials as described herein.

Exemplification [0326] The present disclosure exemplifies compositions, preparations, formulations, nanoparticles, and/or nanomaterials described herein. The present disclosure also exemplifies methods of preparing, characterizing, and validating compositions, preparations, formulations, nanoparticles, and/or nanomaterials described herein. Example 1: Materials and Methods [0327] The present Example provides exemplary materials and methods of preparing, characterizing, and validating compositions, preparations, nanoparticles, and/or nanomaterials described herein. LNP preparations [0328] Among other things, the present Example provides for exemplary LNP preparations. [0329] Lipid nanoparticle components were dissolved in 100% ethanol at specified lipid component molar ratios. Nucleic acid (NA) cargo was dissolved in 10 mM citrate, 100 mM NaCl, pH 4.0, resulting in a concentration of NA cargo of approximately 0.22 mg/mL. In some embodiments, NA cargos include both a functional NA and a reporter DNA barcode mixed at mass ratios of 1:10 to 10:1 functional NA to barcode. As described herein, a NA can be a siRNA, an anti-sense, an expressing DNA, or mRNA. [0330] LNPs were prepared with a total lipid to NA mass ratio of 11.7. LNPs were formed by microfluidic mixing of the lipid and NA solutions using a Precision Nanosystems NanoAssemblr Spark or Benchtop series Instruments, according to the manufacturers protocol. A ratio of aqueous to organic solvent of approximately 2:1 or 3:1 was maintained during mixing using differential flow rates. After mixing, LNPs were collected, diluted in PBS (approximately 1:1 v/v). Further buffer exchange was conducted using dialysis in PBS at 4 °C for 4 to 24 hours against a 20kDa filter. After this initial dialysis, each individual LNP preparation was characterized via dynamic light scattering (DLS) to measure the size (e.g., diameter) and polydispersity. In addition, pKa of a subpopulation of LNPs was measured via a 2-(p-toluidino)-6-napthalene sulfonic acid (TNS) assay. LNPs falling within specific diameter and polydispersity ranges were pooled, and further dialyzed against phosphate buffer saline (PBS) at 4 °C for 1 to 4 hours against a 100kDa dialysis cassette. After the second dialysis, LNPs were sterile filtered using 0.22 ^M filter and stored at 4 °C for further use. LNP characterization [0331] DLS - LNP hydrodynamic diameter and polydispersity index (PDI) were measured using high throughput dynamic light scattering (DLS) (DynaPro plate reader II, Wyatt). LNPs were diluted 1X PBS to an appropriate concentration and analyzed. Concentration & Encapsulation Efficiency [0332] Concentration of NA was determined by Qubit microRNA kit (for siRNA) or HS RNA kit (for mRNA) per manufacturer’s instructions. Encapsulation efficiency was determined by measuring nucleic acid concentration in unlysed and lysed LNPs. pKa [0333] A stock solution of 10 mM HEPES (Sigma Aldrich), 10 mM MES (Sigma Aldrich), 10 mM sodium acetate (Sigma), and 140 nM sodium chloride (Sigma Aldrich) was prepared, and pH was adjusted using hydrogen chloride and sodium hydroxide to a range of about pH 4-10. Using four replicates for each pH value, 140 μL pH-adjusted buffer was added to a 96-well plate, followed by the addition 5 μL of 2-(p-toluidino)-6- napthalene sulfonic acid (60 μg/ mL). 5μL of LNP was added to each well. After 5 min of incubation under gentle shaking, fluorescence was measured using an excitation wavelength of 325 nm and emission wavelength of 435 nm (BioTek Synergy H4 Hybrid). LNP Administration [0334] Male and female mice aged approximately 8-12 weeks were used for the studies described by the present Example. Each mouse was temporarily restrained, and pooled LNP was administered intravenously (IV) via tail vein injection in up to five animals per experiment. Age- matched mice were also used to administer vehicle (1X PBS) via tail vein injection in up to three animals per experiment. At 72 hours post-dose, tissues including liver, spleen, bone marrow, kidney, lung, muscle, and blood were collected for analysis. Flow [0335] Liver, kidney, lung, and muscle tissues were mechanically, and then enzymatically digested using a mixture of proteinases, then passed through a 70uM filter to generate single cell suspensions. Spleen tissues were mechanically digested to generate single cell suspensions. All tissues were treated with (Ammonium-Chloride-Potassium) ACK buffer to lyse red blood cells, and then stained with fluorescently-labeled antibodies for flow cytometry and fluorescence- activated cell sorting (FACS). Commercially available antibodies were used. Using a BD FACSMelody (Becton Dickinson), samples were acquired via flow cytometry to generate gates prior to sorting. In general, gating structure is size ^ singlet cells ^ live cells ^ cells of interest. T cells were defined as CD45+CD3+, monocytes are defined as CD45+CD11b+, and B cells are defined as CD45+CD19+. Endothelial cells were defined as CD31+, monocytes and Kupffer cells as CD45+CD11b+ and hepatocytes as CD31-/CD45-. For siRNA studies, downregulation of the target gene was gated. For mRNA studies, upregulation of the target gene was gated. Tissues from vehicle-dosed mice were used to set the gates for sorting. Up to 1 million cells of each cell subset with the correct phenotype were sorted into PBS. After sorting, cells were pelleted via centrifugation and DNA is extracted using Quick Extract DNA Extraction Solution (Lucigen) according to manufacturer’s protocol. Following DNA extraction, DNA was stored at -20°C. Barcoding Sequencing [0336] DNA (genomic and DNA barcodes) were isolated using QuickExtract (Lucigen) and sequenced using Illumina MiniSeq as described herein, normalizing frequency DNA barcode counts in FACS isolated samples to frequency in injected input. These data were plotted as ‘Normalized Fold Above Input’ (data not shown).
