Abstract: The present invention describes a novel antimicrobial ion delivery system (IDS) article, methods of making the article, and its applications in cleaning dentures and dentistry equipment. The novel IDS entails a source of oligodynamic metal ions embedded in a matrix that allows for the release of metal ions in water at concentrations that are biocidals and prevent biofilm formation. The preferred IDS contains particles made of metallic alloys and bound to a matrix that ensures the controlled release of ions in water. The novel IDS is safe for use in humans and it is environment friendly and biodegradable.

Abstract: We disclose novel classes of alloy nanocompositions that have superior decontaminant properties which are derived from their superior immediate and residual biocidal properties. By decontaminant properties it is understood that the preferred compositions are antiseptics, disinfectants, sanitizers, and/or sterilizers. By biocidal properties it is understood that the preferred compositions are excellent antimicrobials, antivirals, antifungals, and sporicidals. The preferred compositions have superior immediate and residual biocidal properties in free or bound form and they are safe to humans and environmental friendly. The nanocomposites described herein are in two element, three element or four element combinations. The preferred compositions have additional properties such as they are magnetic and/or they have distinct natural colors. The compositions are produced in different sizes ranging from 5 nm up to 500 nm, and for some other classes above 500 nm.
