US Patent 8394494 Antimicrobial substrates and uses thereof

A new substrate makes it possible to modify surface properties relating to antimicrobial properties. Said substrate has an electron donating surface, characterized in having metal particles on said surface, said metal particles comprising palladium and at least one metal chosen from gold, ruthenium, rhodium, osmium, iridium, and platinum, wherein the amount of said metal particles is from about 0.001 to about 8 μg/cm2. The substrate is suggested for different uses, such as for modifying the hydrophobicity, protein adsorption, adhesion of bacteria, as well as preventing bacterial transmission and in particular preventing nosocomial infections.
