ANTIVIRAL AND ANTIMICROBIAL COATINGS AND METHODS THEREOF CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit of U.S. Patent Application No. 63/163,605, filed March 19, 2021, the disclosure of which is incorporated herein by reference in its entirety. BACKGROUND Antiviral and antimicrobial compounds are chemical compounds that reduce or mitigate the growth or development of viral and microbial organisms, respectively. The use of antiviral and antimicrobial compounds leads to either death or arrested growth of the targeted microorganisms, which include viruses and microbes. Minimizing infections caused by pathogenic microorganisms is a great concern in many fields, such as in medical devices, hospital surfaces/furniture, dental restoration and surgery equipment, healthcare products and hygienic applications, water purification systems, textiles, food packaging and storage, industrial or domestic appliances, aeronautics, etc. Infections are produced by touching, eating, drinking, or breathing substances that contains a pathogen. Generally, these infections are combated with agents that target the pathogen. Particularly problematic, however, are the microorganisms that can rapidly and easily mutate their genes to become resistant to these agents, making their elimination difficult. For instance, Staphylococcus aureus (S. aureus) commonly colonizes human skin and mucosa without causing severe problems, but if the bacteria enter the body, illnesses that range from mild to life-threatening can develop, including skin and wound infections, infected eczema, abscess infections, heart valve infections or endocarditis, pneumonia, and bloodstream infections or bacteremia. Some S. aureus are resistant to methicillin and other β-lactam antibiotics-methicillin-resistant S. aureus (MRSA)—and require alternative types of antibiotics to treat them. There is a need for antiviral and antimicrobial materials that exhibit broad-spectrum antiviral and/or antimicrobial activity and that can used in a variety of environments (e.g., homes, healthcare facilities, schools), surfaces (e.g., wood, stainless steel, marble, glass, and textiles), and applications (e.g., food packaging, water or air filters). The materials can have high kill rate, be viable for weeks, and be non-toxic. This disclosure fulfills these needs and provides further advantages. SUMMARY This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. In one aspect, the present disclosure features a method of inhibiting microorganisms on a surface, including applying to the surface a polymer including a repeating unit, the repeating unit including: (i) a benzimidazolium-containing moiety of Formula (I): (I) wherein: R _1AA is independently selected from the group consisting of H, methyl, trifluoromethyl, alkyl, perfluoroalkyl, heteroalkyl, alkoxy, perfluoroalkoxy, halo, aryl, heteroaryl group and a polymer; R _2AA is independently selected from the group consisting of hydrogen, any group, and a polymer; R _3AA is independently selected from the group consisting of methyl, trifluoromethyl, alkyl, perfluoroalkyl, heteroalkyl, aryl, aralkyl, a polymer, and no group; and R _5AA is independently selected from the group consisting of hydrogen, any group, and a polymer; wherein at least one of R _1AA , R _2AA , R _3AA , and R _5AA , is a polymer; (ii) an imidazolium-containing moiety having Formula (II): (II) wherein: R _1XX is independently selected from the group consisting of H, methyl, trifluoromethyl, alkyl, perfluoroalkyl, heteroalkyl, alkoxy, perfluoroalkoxy, halo, aryl, heteroaryl group and a polymer; R _2XX is independently selected from the group consisting of hydrogen, any group, and a polymer; R _3XX is independently selected from the group consisting of methyl, trifluoromethyl, alkyl, perfluoroalkyl, heteroalkyl, aryl, aralkyl, a polymer, and no group; and R _5XX is independently selected from the group consisting of hydrogen, any group, and a polymer; wherein at least one of R _1XX , R _2XX , R _3XX , and R _5XX , is a polymer, or any combination thereof. DESCRIPTION OF THE DRAWINGS The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein: FIGURES 1A-1D are a series of graphs showing antimicrobial action of embodiments of polymer coatings of the present disclosure against viruses and bacteria. FIGURE 2 is a scanning electron micrograph of an embodiment of a polymeric coating of the present disclosure. Unlike nano-silver, the polymeric coatings of the present disclosure provide a smooth surface that enhances antimicrobial activity. Cryo-fractured SEM on high surface area carbon (> 3000 m²/g) shows infiltration depths in the range of 0.3- 0.6 μm (300-600 nm). An area loading equivalent to about 1 μm can provide a cohesive coating, while <1 μm coatings can be readily formed on less porous surfaces. FIGURE 3A is a graph of % transmittance as a function of wavelength for a representative polymeric coating of the present disclosure and FIGURE 3B is a thermogravimetric analysis (TGA) scan of the same. FIGURE 4 is a table of embodiments of polymeric coatings of the present disclosure. Water uptake can vary by counterion. The chloride + low functionality variant is very hydrophobic, the chloride or acetate + high functionality variants are hydrophilic, and the nitrate + high functionality variant is an in-between. The hydrophilicity/hydrophobicity can provide differentiation in antibacterial and/or antiviral properties. For example, changes in hydrophilicity can provide alterations in interactions with bacterial cell walls, viral envelopes, and influence polymer mobility. FIGURE 5 is a schematic representation of an antimicrobial and/or antiviral tests. The ISO/JIS standards chosen are considered "gold standard" tests, and are designed to test the antimicrobial properties of non-porous surfaces. The test involves six data points per sample (triplicate + 'plated' twice), and an additional blank/non-coated glass slide control. The antiviral tests performed included soiling (5% blood serum in viral inoculation solution) and included testing for cytotoxicity as a potential confounding variable (all negative). FIGURE 6 is a table of parameters for antimicrobial and/or antiviral tests of embodiments of polymeric coatings of the present disclosure. S. aureus (Gram +) and E. coli (Gram -) were representative in antimicrobial testing for G+ and G- bacteria. Human Coronavirus (229E) was used as a model of enveloped viruses, such as coronaviruses (e.g., SARS-CoV-2). Feline Calcivirus (F-9) was used as a model for non-enveloped viruses, such as respiratory viruses (e.g., the calcivirus family). Ultra-thin films ~0.75-1.5 μm were tested. FIGURE 7 shows tables of antimicrobial testing results for embodiments of polymeric coatings of the present disclosure. FIGURE 8 is a table of kinetic analysis of antimicrobial testing results for embodiments of polymeric coatings of the present disclosure. Unprecedented activity for a surface modification was observed – half-lives for Human Coronavirus (229E), G+, and G- bacteria were demonstrated as little as < 2.1 minutes – a 4-5 log reduction to beyond the detectable limit within 30 minutes. All variants passed JIS/ISO protocols for antibacterial activity (log10 reduction >2 in 24h). Acetate and 1.5 μm "thick" chloride films had better activity – ultra-thin coatings can increase hydrophobicity. FIGURE 9 is a schematic representation of a drip flow reactor.

Examples of polymers are described, for example, in PCT publication nos. WO2013/149328, WO2015/157848, WO2018/026743, and WO2018/023097, each of which is incorporated herein in its entirety. The polymer can effectively render the coated surface bactericidal, virucidal, and/or germicidal, such that microorganisms (e.g., fungi, viruses, and/or microbes [e.g., bacteria or single-cell organisms]) on the surface are killed and/or inhibited on the coated surface. In some embodiments, the polymer can inhibit adhesion of microorganisms on the surface. The polymers of the present disclosure can form a clear, transparent, durable, ultra- thin film on any surface with a variety of solvents, such as non-toxic solvents. The polymeric coatings can provide unprecedented antimicrobial activity. In some embodiments, up to ≥ 99.995% reduction of enveloped viruses, G- bacteria (E. coli), and G+ bacteria (S. aureus) can be seen in ≤ 30 minutes. Half-lives of viruses and bacteria can be on the order less than 10 minutes (e.g., less than 5 minutes, less than 3 minutes). Unlike silver nanoparticles and nanostructured surfaces, the universally applicable, cost-effective, polymeric coatings of the present disclosure do not lose effectiveness under mechanical stress (e.g., through wash/disinfectant cycles). The coated surfaces can have increased smoothness, which can enhance the antimicrobial properties of the surface. Furthermore, the coatings can be non-toxic to humans and the environment; and can be chemically (e.g., to soiling, fouling, UV, disinfectant, and bleach) and mechanically stable. In some embodiments, when the polymer-coated surface is exposed to the microorganism, the number of microorganisms on the surface can be reduced by greater than 99 % after a duration of 24 hours (e.g., less than 24 hours, less than 20 hours, less than 12 hours, less than 6 hours, less than 3 hours, less than 1 hour, less than 30 minutes, less than 20 minutes, less than 10 minutes, or less than 5 minutes). The microorganism can include a fungus (i.e., one or more species of a fungus), a bacterium (i.e., one or more species of a bacterium), a virus (i.e., one or more species of a virus), or any combination thereof. In some embodiments, when the polymer-coated surface is exposed to a fungus, the number of the fungus on the surface can be reduced by greater than 99 % after a duration of 24 hours (e.g., less than 24 hours, less than 20 hours, less than 12 hours, less than 6 hours, less than 3 hours, less than 1 hour, less than 30 minutes, less than 20 minutes, less than 10 minutes, or less than 5 minutes). In some embodiments, when the polymer-coated surface is exposed to a bacterium, the number of the bacterium is reduced by greater than 99 % after a duration of 24 hours. The bacterium can be a gram-positive bacterium, and/or a gram-negative bacterium. The bacterium can be pathogenic.

Together, they may be referred to as moieties. They may also be referred to as the imidazolium or benzimidazolium moieties. The steric crowding of the provided moieties results from the interaction of the R ₃ imidazolium or benzimidazolium groups in relation to relatively "bulky" groups at the R ₁ positions on the aryl ring. Accordingly, as noted above, the R _1AA and R _1XX groups are at least as large as a methyl group. The moieties can be incorporated into a polymer in any manner known to those of skill in the art. Particularly, the moieties can be attached to a polymer chain at any of the R _1AA , R _2AA , R _3AA , R _5AA , R _1XX , R _2XX , R _3XX , and R _5XX positions. As used herein, when an R- group is defined as a "polymer", that R-group location connects one of the moieties to a polymer chain. As discussed further herein, multiple R-groups can be "polymer" and the moieties can be incorporated into a polymer in a number of ways, including as part of the polymer backbone and/or as a pendant. In one embodiment, the moiety M1 is incorporated in the monomer as part of the polymer backbone, as described in further experimental detail below. As used herein, a monomer that is part of the main chain (or backbone) of a polymer is a repeating unit that is connected on at least two ends to the polymer chain. It will be appreciated that the moiety can be the only moiety in the backbone monomer: -[M1] _x . Alternatively, the moiety can be one of a plurality of moieties in the backbone of the monomer: [M1] _x [A] _y [B] _z , As an example of integrating the moiety M1 into the main chain of a polymer, the following exemplary structure of Formula (I-A) is illustrative: (I-A) wherein L _1AA is an optional addition group or groups on either side of the moiety. L _1AA can be any group known to those of skill in the art (e.g., alkyl, aryl, etc.). In one embodiment, the moiety M1 is incorporated as a pendant moiety attached to the backbone of the polymer. As used herein, the term "pendant" refers to a moiety that is attached at only one end to a polymer backbone. It will be appreciated that the moiety may be directly connected to the polymer backbone or there may be additional moieties (e.g., linker groups, L _2AA ) in between the moiety and the polymer backbone. Once again, attachment can come at any of the R _1AA , R _2AA , R _3AA , or R _5AA positions. For example, attachment can be through an R _2AA position on the aryl, as illustrated in Formula (I-B) below. L _2AA is an optional linker group connecting the main chain of the polymer, P _1AA , to the moiety. L _2AA can be any group known to those of skill in the art.

(I-C) In one embodiment, the moiety M2 is incorporated as a pendant moiety attached to the backbone of the polymer. It will be appreciated that the moiety may be directly connected to the polymer backbone or there may be additional moieties (e.g., linker groups, L _2AA ) in between the moiety and the polymer backbone. Once again, attachment can come at any of the R _1AA , R _2AA , R _3AA , or R _5AA positions. For example, attachment can be through an R _2XX position on the aryl, as illustrated in Formula (II-A) below. Formula (II-A) Similarly, attachment can be through an R _3XX position on the imidazolium, as illustrated in Formula (II-B) below.

Formula (II-B) Given the multiple available locations on the moieties for attachment to a polymer main chain, the moieties can be attached to multiple polymer chains (e.g., as part of a crosslink). An exemplary embodiment illustrating crosslinking between two polymer chains, P _1XX and P _2XX , via the R _3XX positions, is illustrated in Formula (II-C) below. It will be appreciated that the crosslinking capabilities of the moieties are not limited to the illustrated embodiment. Formula (II-C) In one embodiment, the moiety M1 is grafted onto an already-formed polymer. For example, using a benzimidazole with a monosubstituted R _3AA position (Formula I-D), mixed with P _1AA and heated can produce a pendant benzimidazolium (Formula I-C) connected at the formerly vacant R _3AA position. Examples of P _1AA include alkylhalide-containing polymers such as chloromethylated polysulfone and poly(chloromethylstyrene), including perfluorinated polymers containing haloalkyl groups. In addition, perfluorinated sulfonyl halide-containing polymers, or polymers containing acyl halides can be functionalized using this method. Formula (I-D) Alternatively, the moiety M2 is grafted onto an already-formed polymer using an imidazole with a monosubstituted R ₃ position (Formula II-D) to produce the pendant imidazolium (Formula II-C).

The benzimidazolium-containing moieties can be incorporated into a polymer in any manner known to those of skill in the art. Particularly, the moieties can be attached to a polymer chain at any of the R ₁ , R ₂ , R ₃ , or R ₅ positions.

ANTIMICROBIAL ACTIVITY ASSESSMENT The overall antimicrobial test procedure is shown in FIGURE 5. The present Example was conducted based on two different lots of polymers with different degrees of methylation (dm). The structures of the polymers are shown in Schemes 1 and 2 below. These are hereafter noted as high (91%) and low (57%) dm. Polymers in the iodide form were dissolved at 2 wt% in 50:50 (v/v) methanol:acetone by heating at 40 ºC with stirring and then precipitated respectively in a 1 M aqueous solution of the desired anion: i.e., sodium chloride, sodium nitrate and ammonium acetate. The precipitated, anion-exchanged polymers were filtered, washed with water and dried (80 ºC, 12 h). Solutions for casting were done by dissolving with stirring at 40 ºC. The high dm polymer was dissolved in pure methanol at 0.7 wt% while the low dm polymer was dissolved in 88:12 (v/v) methanol:acetone. Untreated microscope slides (AmScope BS-50P, clear glass, ground edge, 1"x3") were cleaned prior to use by ultrasonication in methanol at room temperature for 30 min. A 1 mL aliquot of a given polymer solution was drop-cast onto the glass slide and dried at room temperature in the fume hood overnight. Referring to FIGURES 2 (micrograph), 3A (transmission), and 3B (TGA), the polymer-coated samples (high dm) were smooth, clear, and transparent.

Anti-Viral Testing ISO 21702 provides a test method for the quantitative evaluation of virucidal activity on plastics and other non-porous surfaces. Products tested are intended to be treated antiviral products, that are tested against the specified virus. The basis of the test method is the incubation of the viral inoculum in contact with the test sample for a duration of 24 hours without drying of the inoculum. Following this exposure, the inoculated virus is recovered, and the concentration of the infective virus is determined. The antiviral performance is determined by a comparison of the recovered virus from the untreated material and treated material after the 24-hour incubation. The antimicrobial performance is reported as both the Log10 and % Reduction relative to the untreated control sample.

DETAILED ANTIBACTERIAL AND ANTIVIRAL TESTS AND RESULTS. ISO 22196: Antibacterial test A method of evaluating the antibacterial activity of antibacterial-treated plastic products including intermediate products). It is not intended to be used to evaluate the effects and propagation of bacteria on plastics without antibacterial treatments. Antimicrobial activity is determined in the following manner: R = (Ut -U0) - (At-U0) = Ut - At Where R is the antibacterial activity; U0 is the average of the common logarithm of the number of viable bacteria, in cells/cm2, recovered from the untreated test specimens immediately after inoculation; Ut is the average of the common logarithm of the number of viable bacteria, in cells/cm2, recovered from the untreated test specimens after 24 h At is the average of the common logarithm of the number of viable bacteria, in cells/cm2, recovered from the treated test specimens after 24 h. For purposes of common reference, the % reduction is also reported in the notes section for each sample result. Legend CFU = colony forming unit (typically cited per unit volume or surface area). CFU is determined by bacterial plating of the test samples according to the specified method, followed by counting of the resultant colonies. Untreated Control (UTC) - untreated control sample material used to demonstrate normal test performance, showing robust microorganism growth. Interval - represents the point or time point from which the result value was determine; T0 indicates that the result is from the soonest possible time from inoculation to recovery of the inoculated sample (typically < 5 min). Result - the result is the measure of change or abundance. Result units indicate the actual measurements, frequently relative to a control value depending on the method or test requirements. Notation of changes to the published test method: Several references are made to 'Plate count agar' for the test method plating following neutralization and recovery of the bacterial from the test samples. As standard practice, counts are performed on appropriate plate media such as Nutrient agar, tryptic soy agar, or as required by the specific organism tested. The published standard refers to incubation conditions of 35 ± 1 °C. Standard microbiological practice with other international methods is for incubations to occur at 37 ± 1 °C. The test conditions performed will be conducted at 37 ± 1 °C unless specified for other temperature conditions. Expanded Uncertainty for the test method of k=2 is for a 95% confidence of Log10 (0.136). Uncertainty Values in CFU are obtained by converting CFU counts (C1) to Log10 values (Log10 C1); multiply this result by the Expanded Uncertainty (Log10 C1*EU), then add and subtract from the Log10 value (Log C1 ± (Log10 C1*EU)); convert back by taking the anti-log (lx10^ (Log C1 ± Log10 C1*EU)) which provides the upper and lower limits of 95% confidence in CFU. Stated Method Standard For ISO 22196, an interlaboratory test demonstrated a results with Standard deviation of Log10(0.45) or ~ 1/2 log. This equates to a - mean value ± 50 % reduction. Conditions for a valid test When the three conditions are satisfied, the test is deemed valid. If all conditions are not met, the test is not considered valid and the specimens shall be retested. The logarithmic value of the number of viable bacteria recovered immediately after inoculation from the untreated test specimens shall satisfy the following requirement: (Lmax-Lmin)/(Lmean)<= 0.2 Where: Lmax is the common logarithm (i.e., base 10 logarithm) of the maximum number of viable bacteria found on a specimen Lmin is the common logarithm of the minimum number of viable bacteria found on a specimen; Lmean is the common logarithm of the mean number of viable bacteria found on the specimens. Abstract The ISO-22196 test method is designed to measure the antimicrobial properties of solid or hard surface treated test samples incubated with selected microorganisms. The basis of the test method is the incubation of the bacterial inoculum in contact with the test sample for a duration of 24 hours without drying of the inoculum. Following this exposure, the inoculated bacteria are recovered and the concentration of the organisms is determined. The antimicrobial performance is determined by comparison of the recovered organisms from the untreated material and treated material after the 24 hour incubation.

JIS Z 2801 - Antibacterial products - Test for antimicrobial activity and efficacy JIS Z 2801 specifies a method of evaluating the antibacterial activity of plastic products. It is a method commonly used for evaluating the antimicrobial properties of many material types that can range from coated surfaces or those of monolithic composition. The basis of the test method is the incubation of the microorganism inoculum in intimate contact with the test substance on a flat horizontal surface for 24 hours. Following this exposure, a sample of the inoculum is recovered and the concentration of the organisms is determined. The antimicrobial performance is determined by comparison of the recovered organisms from the untreated inoculum-only test substances after the selected time points and treated test substance after the selected time points. It is not intended to be used to evaluate the effects and propagation of bacteria on plastics without antibacterial treatments. Testing Inoculum Preparation Following an overnight incubation of the test bacteria, a transfer to the inoculation solution is performed. Using a sterile inoculating loop, transfer one loop of the test bacteria into a small amount of 1/500 NB prepared. A dilution of this suspension with 1/500 NB is created as appropriate to establish an estimated bacterial concentration, to obtain a bacterial concentration that is between SES CFU / mL and 2E6 CFU / mL, with a target concentration of 1E6 CFU /mL. Inoculation of test specimens • The surface to be tested is the exposed outer surface of the product. • Pipette 0.2 mL of the test inoculum prepared onto the test surface. • Cover the test inoculum with a piece of film that measures 40 mm x 40 mm and gently press down. on the film so that the test inoculum spreads to the edges. • Make sure that the test inoculum does not leak beyond the edges of the film. • After the specimen has been inoculated and the cover film applied, replace the lid of the Petri dish. Incubation of the inoculated test specimens The standard procedure for incubation of the inoculated specimens is to incubate the Petri dishes containing the inoculated test specimens (including half of the untreated test specimens) at a temperature of (37 ± 1) °C and a relative humidity of not less than 90 % for (24 ± 1) h, unless otherwise noted. Recovery of bacteria from test specimens. Immediately after inoculation, process half of the untreated test specimens by adding 5 mL of a suitable neutralizer to the Petri dish containing the test specimen. Test specimens after incubation After the incubation, process the remaining test specimens. Proceed immediately to count the viable bacteria recovered from the test specimen.

ISO 21702: antiviral test The ISO 21702 provides a test method for the quantitative evaluation of virucidal activity on plastics and other non-porous surfaces. Products tested are intended to be treated antiviral products, that are tested against the specified virus. The basis of the test method is the incubation of the viral inoculum in contact with the test sample for a duration of 24 hours without drying of the inoculum. Following this exposure, the inoculated virus is recovered, and the concentration of the infective virus is determined. The antiviral performance is determined by a comparison of the recovered virus from the untreated material and treated material after the 24-hour incubation. The antimicrobial performance is reported as both the Log10 and % Reduction relative to the untreated control sample. Results and Discussion Results are provided in the Result Data Tables Testing was conducted with soiling by incorporation of 5% serum to the viral inoculation solution. ISO 21702 specifies a method of evaluating virucidal activity of non-porous surfaces. Each product was tested using clean test condition (no additional soil). Unless otherwise specified, secondary effects of antibacterial treatments, the measured antimicrobial performance, or the durability of a measured activity are not covered by the standard. The standard is not intended to be used or referenced as a method to document or claim antimicrobial performance unless indicated by the test report. The determinations of product performance within a given environment can vary dramatically, and must be specifically documented and then determined within the context of a specific project plan. Methods Project- Specialized Organism Culturing- Virus Cell culturing for non-standard virus used in a given test method. For each virus, the necessary media, and culture conditions are employed according to standard requirements established by the lab. ISO 21702 - Measurement of antiviral activity on plastics and other non-porous surfaces The ISO 21702 method is used to evaluate the virucidal efficacy of a non-porous product. Testing can incorporate different exposure times, soiling, and virus types and other variables according to the test standard or specific needs of a product. The most common test conditions employ the standard method protocol requiring a 24-hour exposure to the test material depending on the intended use of the product. Test virus are prepared in advance of the testing followed by a determination of viral titer. The inocula created is then utilized as the inocula for the exposure of the test material to the virus. ISO 21702 Inherent Cytotoxicity Optimization Antiviral testing requires the use of host cells for propagation and enumeration of the viral concentration. The host cells must be viable and biologically intact to allow viral infection. Successful infection by the virus results in the replication and ultimate lysis and loss of the host cell. This process provides the means by which viruses are measured. Cytotoxicity of the host cell as a result of any chemical carry-over from the test sample can affect the biological viability of the host cell and interfere with needed processes subsequent to the exposure of the cells to the virus. This interference is generally considered as the inherent cytotoxicity of the test sample. The test is conducted by incubating the test sample for 30 seconds with the neutralizing recovery solution, followed by exposure of the host cells to eight concentrations of the recovered solution. Inherent cytotoxicity is identified by the loss of the cell culture viability. Testing Inoculum Preparation A known viral titer suspension is prepared to a concentration of at least 1E6 TCID5O / mL. Passaged of the virus are not used beyond ten passes from the original seed culture. Experimental Conditions Following inoculation, the samples are incubated at 25 C ± 1 °C (unless otherwise specified). The incubation is conducted to prevent the inoculum from drying while in contact with the test surface. Following the incubation period, the virus is recovered in neutralizing media and then diluted for culturing. Recovery of virus from test specimens. Two time points are created for each test item, a washout of the inoculated sample is collected immediately after inoculation by addition of the selected neutralizer solution by placing the sample into a vial and adding 10 mL of the neutralizer, followed by vortexing. A second recovery is created following the intended incubation time (24 hr), after which the sample is placed into a vial with 10 mL of the neutralizing solution and vortexed. Following the test sample neutralization, aliquots of the sample are recovered and used to determine the infective titer following the respective incubation periods.

Each test sample is prepared in triplicate for each time point. As available, the samples are cut into a piece approximately 50 mm x 50 mm. Sample variability is accommodated as needed for the standard test; notes regarding differences in the sample characteristic are recorded in the report summary. Ideally, the test sample is flat and non-hydrophobic and allow layering of the inoculum over the sample surface. Calculations End-point dilutions are conducted with the recovered virus inocula using serial log10 dilution factors. TCIDSO (Spearman-Karber; modified by M.A. Ramakrishnan) is used to determine the concentration of the inoculated virus based on the outcome of the end-point dilution resulting in the CTE of the host cells. It represents the end-point dilution (average) of the host cell monolayers exhibiting the CTE. Log10 50% end-point Dilution= - [(total number of CTE wells/ total number of dilution replicates) + 0.5] x log dilution factor R = - [Total CTE / replicate count per dilution)+ 0.5] x Log dilution factor R = The log 50% end-point dilution Total CTE - is the average of the common logarithm of the number of viable virus, in cells/cm2, recovered from the untreated test specimens immediately after inoculation; Replicate count per dilution - the numbers of well replicates inoculated at each dilution Log dilution factor - is the dilution factor used for each serial dilution (typically 10x or log10(10) = 1) Antiviral Activity Value R= U(t24)-C(t24)R = the antiviral activity value C(t24) = the common logarithm average of 3 infectivity titer values after 24 hours from the untreated material U(t24) = the common logarithm average of 3 infectivity titer values after the contact time (24 hr) with the treated (test) sample Statistical Methods Replicate data are utilized in the calculation by the Spearman-Karber method, no additional statistical analysis is conducted.

EXAMPLE 4. ANTIFOULING TESTS

Test polymeric coupons are prepared by spraying a 5 wt% methanolic solution of a partially demethylated polymer material of the present disclosure, in mixed chloride/iodide form, onto glass slides, to afford continuous films of a given thickness and a given mass loading. Coupons were then subjected to biofilm growth conditions and cell enumeration as per ASTM E2647-13, a standard test method for quantification of Pseudomonas aeruginosa biofilm grown using drip flow biofilm reactor with low shear and continuous flow, incorporated herein by reference in its entirety.

Specifically, ASTM E2647-13 specifies the operational parameters required to grow a repeatable Pseudomonas aeruginosa biofilm close to the air/liquid interface in a reactor with a continuous flow of nutrients under low fluid shear conditions. The resulting biofilm is representative of generalized situations where biofilm exists at the air/liquid interface under low fluid shear rather than representative of one particular environment.

The test method uses the drip flow reactor. The drip flow reactor (DFR) is a plug flow reactor with laminar flow resulting in low fluid shear. The reactor is versatile and can also be used for growing and/or characterizing biofilms of different species.

This test method describes how to sample and analyze biofilm for viable cells. Biofilm population density is recorded as log colony forming units per surface area.

The test method is used for growing a repeatable P. aeruginosa biofilm in a drip flow reactor. The biofilm is established by operating the reactor in batch mode (no flow of nutrients) for 6 h. A mature biofilm forms while the reactor operates for an additional 48 h with a continuous flow of nutrients. During continuous flow, the biofilm experiences very low shear caused by the gravity flow of media dripping onto a surface set at a 10° angle. At the end of the 54 h, biofilm accumulation is quantified by removing coupons from the reactor channels, rinsing the coupons to remove the planktonic cells, scraping the biofilm from the coupon surface, disaggregating the clumps, then diluting and plating for viable cell enumeration. The experimental setup is as illustrated in FIGURES 9 and 10. Purity of Water—All reference to water as diluent or reagent shall mean distilled water or water of equal purity. Culture Media: Bacterial Liquid Growth Broth—Tryptic Soy Broth (TSB)7 is recommended. Two different TSB concentrations are used in the test method, 3000 mg/L for the inoculum and batch reactor operation and 270 mg/L for the continuous flow reactor operation. Bacterial Plating Medium—R2A agar7 is recommended. Buffered Water—0.0425 g/L KH2PO4 distilled water, filter sterilized and 0.405 g/L MgCl·6H2O distilled water, filter-sterilized (prepared according to Method 9050 C.1a). Pseudomonas aeruginosa (ATCC 700888) is the organism used in this test. Aseptically remove an isolated colony from an R2A plate and inoculate into 100 mL of sterile bacterial liquid growth broth (3000 mg TSB/L). Incubate bacterial suspension in an environmental shaker at 35 ± 2 °C for 20 to 24 h. Viable bacterial density should equal 108 CFU/mL and may be checked by serial dilution and plating. Procedure The Batch Phase: Place the cooled reactor in a level position on the bench top. Aseptically add 15 mL of sterile 3000 mg TSB/L and 1 mL of inoculum to each channel. Tighten each channel lid securely with nylon screws. Incubate the reactor system in batch mode at room temperature (2162°C) for 6 h, in the level position. Remove foil from the effluent tubing and attach end into a waste carboy. Do not unclamp until continuous flow phase. Preparation for Continuous Flow Phase: Prepare continuous flow nutrient broth by adding sterilized bacterial liquid growth medium to 20 L sterile reagent grade water so that final concentration is equal to 270 mg TSB/L (see 7.2.1). That is, dissolve and sterilize a broth concentrate in a smaller volume of water to prevent caramelization that can occur under the lengthy sterilization times required for large volumes. Aseptically pour the concentrated medium into the carboy of sterile water to make a total of 20 L. Adjust Reactor Angle (FIGURE.11): Measure a, the length of the reactor base, in cm. Angle (x) is 10°. Calculate y using the following equation: y – a[sin (x)]) where: a = measured length of reactor base in cm, x = angle (10°), and y = difference between length of b and length of c in cm. Decide upon the lengths of b and c to obtain the required difference (y). Use the following equation: Y = b-c where: b = measured length (cm) from bottom corner of influent end of reactor base to laboratory surface, c = measured length (cm) from bottom corner of effluent end of reactor base to laboratory surface, and y = difference between length of b and length of c in cm. Unclamp the effluent tubing and attach the legs to the DFR. Adjust the legs of the reactor chamber until the required lengths (b and c) are achieved so that it slopes downward 10°. Continuous Flow Phase: Aseptically connect the influent nutrient tubing line to the carboy containing the continuous flow nutrient broth. Feed each line through a pump head and connect a sterile needle on the end of each line. Aseptically attach the influent tubing by inserting the sterile needle through the Mininert valves in the channel lids. Turn on the pump, allowing media to slowly drip onto the bacterial cells attached to the coupon. A continuousflow of nutrients is pumped into the reactor through a pump set at a flow rate equal to 200 mL/h (50 mL/h per channel). The media should flow downward from the influent port to the effluent port. Periodically check the reactor for proper drainage and leaks. If problems occur, visually inspect the influent port and the tubing for bacterial plugging. The reactor is operated in CF mode for 48 h. Sampling the Biofilm: Prepare sampling materials: vortex, homogenizer, sterile beakers, sterile centrifuge tubes, culture tubes, pipettes, empty sterile petri dish, sterile spatulas, and flame sterilized stainless steel hemostat or forceps. Loosen channel lid screws with gloved hands and lift channel lid up. Aseptically remove one of the coupons by gently lifting up the coupon with sterile hemostat. Hold coupon over a sterile petri dish while carrying to the sampling area. Hold the coupon with flame sterilized hemostat being careful not to disturb the attached biofilm. Rinse the coupon to remove planktonic cells: Gently immerse coupon into the centrifuge tube containing 45 mL sterile buffered water with a fluid motion until slide is completely covered. Immediately reverse motion to remove the slide, being careful not to agitate liquid and biofilm. Remove the biofilm from the coupon: Scrape biofilm-covered coupon surface in a downward direction for approximately 15 s, using the flat end of a sterile spatula or scraper, into the beaker containing 45 mL of sterile dilution buffer. Rinse the spatula or scraper by stirring it in the beaker. Repeat the scraping and rinsing process 3 to 4 times, ensuring full coverage of the coupon surface. Hold the coupon at a 60° angle over the sterile beaker and pipette 1 mL of sterile buffered water over the top surface of the coupon. Repeat for a total of 5 rinses. The final volume in the beaker is 50 mL. Analyze the Biofilm Sample: Homogenize the scraped biofilm sample in the beaker at 20,500 ± 5000 r/min for 30s. If more than one biofilm sample is taken, rinse the homogenizer probe between each new sample as follows: Homogenize a dilution blank for 30s at 20,500 ± 5000 r/min, homogenize a tube containing 70 % ethanol for 15 s, then remove the probe and let the probe sit in the ethanol tube for 1 min. Shake any remaining ethanol off the probe, reattach probe, and homogenize a dilution blank for 30s. Homogenize a third dilution blank and then homogenize the next sample beaker. Homogenizing the sample disaggregates the biofilm clumps to form a homogeneous cell suspension. Improper disaggregation could result in an underestimation of the viable cells present in the sample. Perform serial 10-fold dilutions on the sample using sterile culture tubes. Plate each dilution in duplicate for colony growth using an accepted plating technique such as spread or spiral plating (Practice D5465). Incubate the plates for 17 to 20 h at 35 ± 2 °C. Cell Enumeration: Count the appropriate number of colonies according to the plating method used. Calculate the arithmetic mean of the colonies counted on the duplicate plates. The log density for one coupon is calculated as follows: LOG ₁₀ (CFU/cm ² ) = LOG ₁₀ [(X/B)(V/A)(D)] where: X = mean CFU, B = volume plated, V = volume scraped into, A = surface area scraped, and D = dilution. Calculate the overall biofilm accumulation by calculating the mean of the log densities. EXAMPLE 4.
