We claim: 1. A method of providing an anti-biocontaminant effect to a target material comprising: preparing a colloidal suspension of one or more anti-biocontaminant metals, gelatin, and a redox agent in a colloidal medium; dispersing the colloidal suspension onto a support structure thereby forming an anti-biocontaminant composition including the support structure, the one or more anti-biocontaminant metals, gelatin, and the redox agent; and applying the anti-biocontaminant composition to the target material. 2. The method of claim 1, further comprising drying the anti-biocontaminant composition prior to applying the composition to the target material. 3. The method of claim 2, wherein the dispersion of the colloidal suspension is a liquid application. 4. The method of claim 1, further comprising drying the target material after applying the anti-biocontaminant composition to the target material. 5. The method of claim 1, wherein the dispersion of the colloidal suspension is a gaseous application. 6. The method of claim 1, wherein the metals are selected from the group consisting of silver, copper, manganese, nickel, tin, zinc, and brass. 7. The method of claim 1, wherein the anti-biocontaminant metals include one or more of ionic metals, colloidal metals, and metallic metals. 8. The method of claim 1, wherein the target material is selected from the group consisting of woven and non-woven products, plastic, synthetic fibers, natural fibers, thermoplastic polymers, paper, cloth, mud bath products, leather, medical wipes, catheters, dust masks, sipping straws, filters, canteens, and metal. 9. The method of claim 1, wherein the anti-biocontaminant composition is applied to the target material by a method selected from the group consisting of spin coating, dip coating, die coating, chemical vapor deposition, curtain coating, incipient wetness impregnation, vacuum impregnation, and low temperature impregnation method. 10. The method of claim 1, wherein the support structure is porous. 11. The method of claim 1, wherein the support structure is non-porous. 12. The method of claim 10, wherein the support structure includes one or more of alumina, alumina gel, pseudoboehmite, gamma, chi-rho, eta, and bayerite alumina. 13. The method of claim 1, wherein the redox agent includes sodium thiosulphate. 14. The method of claim 1, wherein the one or more anti-biocontaminant metals include one or more metal salts. 15. The method of claim 14, wherein the one or more metal salts include one or more of silver nitrate, silver fluoride, and silver chloride. 16. The method of claim 1, wherein the colloidal suspension includes between about 1% to about 4% by mass of the one or more anti-biocontaminant metals. 17. The method of claim 2, wherein drying the composition includes drying the composition at 150° C. for about 1 hour. 18. The method of claim 2, wherein drying the composition includes drying the composition at 150° C. in the presence of a desiccant silica gel. 19. The method of claim 2, wherein drying the composition includes drying the composition at between about 240° C. to about 260° C. for between about 3-4 hours. 20. The method of claim 1, further comprising treating composition with one or more of methyl orange and methyl violet.
