| abstract |
The present invention relates to materials having antimicrobial properties, the materials comprising a polymer in which a synergistic combination of at least two metal oxide powders is incorporated, the synergistic combination comprising a mixed oxidation state oxide of a first metal and a second metal a single oxidation state oxide that is substantially uniformly incorporated into the polymer, wherein the powders have substantially different specific gravities and substantially similar bulk densities and wherein after the materials are exposed to moisture, such The ions of the metal powder are in ionic contact. Also provided are methods of making such materials and uses thereof, including the use of or against the activity of microorganisms or microorganisms. |
