  • Patent number: 6264936
    Abstract: 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 antimicrobial coating or layer is a unique combination of an organic matrix immobilized on the surface of the substrate to having biocidal metallic 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 provided.

  • Patent number: 6180584
    Abstract: The present invention relates to a composition that, when applied to a substrate, forms an adherent, transparent, water insoluble polymeric film on the substrate surface that provides sustained antimicrobial disinfecting action for prolonged periods, without the necessity for reapplication. The coating provides surface disinfecting action by a contact-killing mechanism, and does not release its components into contacting solutions at levels that would result in solution disinfection. The polymeric film formed by the composition of the invention can be removed by treatment with dilute alcoholic base.

  • Patent number: 6126931
    Abstract: Contact killing antimicrobial articles, devices and formulations are described which kill microorganisms on contact. The articles, devices or formulations contain a non-leaching antimicrobial material which is a unique combination of an organic matrix having biocidal metallic materials non-leachably associated with the matrix. The antimicrobial material may used to form an antimicrobial coating or layer on a surface of the article or device, or may be dispersed in a vehicle or carrier to form a topical antiseptic or disinfectant, or solid shape having contact killing antimicrobial properties. When a microorganism contacts the article, device, or formulation, the biocidal metallic material is transferred to the microorganism in amounts sufficient to kill it.
