ABSTRACT:
Structures treated with a microbiological interception enhancing agent comprising of a water-soluble cationic material having a counter ion associated therewith at specific sites on the cationic material, in combination with a biologically active metal salt, wherein the counter ion associated with the cationic material preferentially precipitates with at least a portion of the cation of the biologically active metal salt such that precipitation of the biologically active metal cation and the counter ion associated with the cationic material occurs in proximity to the cationic material are disclosed herein. The microbiological interception enhancing agent may be incorporated into articles of commerce by treating the starting materials of the structure or by applying the microbiological interception enhancing agent on to at least one surface of the article.
