A star polymer with light-activated enhanced antimicrobial functionality that can comprise a plurality of non-degradable copolymer arms comprising respective first ends and respective second ends. The respective first ends can be crosslinked to form a vinyl polymer core and the respective second ends can have antimicrobial functionality. Further, the polymer can comprise a singlet oxygen generator loaded within the vinyl polymer core. The singlet oxygen generator can generate a singlet oxygen species in response to light.

A method for imparting to an article or product antimicrobial activity, including a step of applying an antimicrobial agent containing an antimicrobial polyaminosilane to the article or product. The antimicrobial polyaminosilane is prepared by subjecting an aminosilane monomer to a hydrolysis and condensation reaction. The antimicrobial polyaminosilane thus prepared is free of halide ions.

Total synthesis and evaluation of key analogs of vancomycin containing single-atom changes in the binding pocket, as well as their peripherally modified, N-(hydrophobe-substituted) derivatives exemplified by a N-4-(4′-chlorobiphenyl)-methyl derivative and their pharmaceutically acceptable salts. Their evaluation indicates the combined pocket and peripherally modified analogs exhibit a spectrum of antimicrobial activity and potencies against both vancomycin-sensitive and vancomycin-resistant bacteria, and likely benefit from two independent and synergistic mechanisms of action.

An antimicrobial medical device that includes a substrate having a metal surface that is made from a metal or metal alloy that may include stainless steel, cobalt and titanium. Disposed on the metal surface is a first antimicrobial oxide layer that includes an antimicrobial metal that may include silver, copper, zinc and combinations thereof. The atoms of antimicrobial metal in the first antimicrobial oxide layer are of a first concentration. The first antimicrobial oxide layer is positioned in a direction opposite that of the metal surface. The device further includes a second antimicrobial oxide layer that includes an antimicrobial metal that may be silver, copper, zinc and combinations thereof. The atoms of the antimicrobial metal present in the second antimicrobial oxide layer are of a second concentration. The first concentration and the second concentration are not equal.
