CONTACT-KILLING NON-LEACHING ANTIMICROBIAL MATERIALS

摘要

An antimicrobial material is described which can be used to form on the surface on a substrate a non-leaching antimicrobial coating or layer which kills microorganisms on contact. The non-leaching antimicrobi al coating or layer is a unique combination of an organic matrix immobilized on the surface of the substrate to having biocidal metall ic materials non-leachably associated with the matrix. When a microorganism contacts the coating or layer, the biocidal metallic material is transferred to the microorganism in amounts sufficient to kill it. Methods of applying the coating or layer to a substrate also are provide d.
