Nanostructured crystalline titaniumdioxide coatings deposited by cathodic arc evaporated on titanium grade five medical implant substrates were demonstrated to exhibit UV-induced photocatalytic activity that can be utilized to provide bactericidal effects against Staphylococcus epidermidis. The photocatalytic activity of the coatings was confirmedvia degradation of Rhodamine B under UV illumination.A 90 %reduction of viable bacteria was achieved in a clinically suitable time of only 2 min with a UVdose of 2.4 J delivered at 365 nm. These results areencouraging for the development of antimicrobialsurfaces in orthopedics and dentistry in order to prevent or treat post-surgical infections.
