Abstract

A cellulose based anti-viral/anti-microbial coating.

Claims (33)

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.
