The coating includes acidic chelating components, reactively bound to a hydrophilic polyurethane prepolymer along with noble metal combinations or antibacterials. The acidic and noble metal combinations can also be incorporated as additives during plastic molding of medical devices. A continuous antibacterial surfaces are provided by such coatings and materials.Other References
