Everyday life is exposed to the risks of contracting severe diseases due to the diffusion of severe pathogens. For this reason, efficient antimicrobial surfaces becomes a need of primary importance. In this work we report the first evidences of a new technique to synthesize an antibacterial coating on Ultra High Molecular Weight Polyethylene (UHMWPE) samples, based on a non-stoichiometric, visible light responsive, titanium oxide. The coating was obtained through laser ablation of a titanium target, then the resulting ions were accelerated and implanted on the samples. The samples where tested against a Staphylococcus aureus strain, in order to assay their antimicrobial efficacy. Results show that this treatment strongly discourages bacterial adhesion to the treated surfaces.
