ENHANCEMENT OF ANTIMICROBIAL SILVER, SILVER COATINGS, OR SILVER PLATINGS

摘要

Antimicrobial metal ion coatings. In particular, described herein are coatings including an anodic metal (e.g., silver and/or zinc and/or copper) that is co-deposited with a cathodic metal (e.g., palladium, platinum, gold, molybdenum, titanium, iridium, osmium, niobium or rhenium) on a substrate (including, but not limited to absorbable/resorbable substrates) so that the anodic metal is galvanically released as antimicrobial ions when the apparatus is exposed to a bodily fluid. The anodic metal may be at least about 25 percent by volume of the coating, resulting in a network of anodic metal with less than 20% of the anodic metal in the coating fully encapsulated by cathodic metal.

主权项

1. A method of forming an enhanced antimicrobial surface, the method comprising:
co-depositing a coating of silver and a cathodic metal onto a substrate surface, wherein the co-deposited coating comprises a mixture of between about 25% and 75% by volume of silver, and between about 25% to 75% by volume of the cathodic metal; and applying ozone to the coated surface for at least 5 minutes.
