A cellulose based anti-viral/anti-microbial coating.
First claim
Opening claim text (preview).
What is claimed is: 1. A cellulose based anti-viral/anti-microbial coating comprising: a cellulose nanomaterial layer; and a tosyl cellulose intermediate layer; and an anti-viral/anti-microbial layer bonded to said intermediate layer. 2. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is covalently bonded to said intermediate layer. 3. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is non-covalently bonded to said intermediate layer. 4. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is Ciprofloxacin. 5. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is Sulfamethoxazole. 6. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is Trimethoprim. 7. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is Isonaizid. 8. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is Metronidazole. 9. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is Daptomycin. 10. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is a combination of Ciprofloxacin, Sulfamethoxazole, Trimethoprim, Isonaizid, Metronidazole and Daptomycin. 11. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is a benzalkonium chloride. 12. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is a hydrogen peroxide-based compound. 13. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is peroxyacetic acid. 14. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer contains chlorine. 15. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is hypochlorite acid. 16. The cellulose based anti-microbial coating of claim 1 wherein said anti-viral/anti-microbial layer is acid. 17. A method of creating an anti-viral/anti-microbial coating on a substrate comprising the steps of: providing a cellulose nanomaterial layer; adding an intermediate layer to said cellulose nanomaterial layer, said intermediate layer is tosyl cellulose; creating an anti-viral/anti-microbial layer on said intermediate layer to create an anti-viral/anti-microbial coating; and applying said anti-viral/anti-microbial coating to a substrate. 18. The method of claim 17 wherein said anti-viral/anti-microbial layer is covalently bonded to said intermediate layer. 19. The method of claim 17 wherein said anti-viral/anti-microbial layer is non-covalently bonded to said intermediate layer. 20. The method of claim 17 wherein said anti-viral/anti-microbial layer is Ciprofloxacin. 21. The method of claim 17 wherein said anti-viral/anti-microbial layer is Sulfamethoxazole. 22. The method of claim 17 wherein said anti-viral/anti-microbial layer is Trimethoprim. 23. The method of claim 17 wherein said anti-viral/anti-microbial layer is Isonaizid. 24. The method of claim 17 wherein said anti-viral/anti-microbial layer is Metronidazole. 25. The method of claim 17 wherein said anti-viral/anti-microbial layer is Daptomycin. 26. The method of claim 17 wherein said anti-viral/anti-microbial layer is a combination of Ciprofloxacin, Sulfamethoxazole, Trimethoprim, Isonaizid, Metronidazole and Daptomycin.
