Patent ID: 7287650

Claim:
An anti-microbial structure comprising of: a dry base structure; and a microbiological interception enhancing agent comprising of a water-soluble cationic material and a biologically active metal salt, said water-soluble cationic material having a counter ion associated therewith on at least a portion of said dry base structure, said biologically active metal salt provided in direct proximity to said cationic material on said base structure whereby the counter ion associated with the cationic material preferentially precipitates with at least a portion of the biologically active metal to generate a colloidal metal precipitate adjacent the cationic material, said colloidal metal precipitate residing on said dry base structure; wherein said dry base structure comprises a plurality of fibers wherein said plurality of fibers are coated with or contain said microbiological interception enhancing agent wherein the water-soluble cationic material is a polymer.
