An antibacterial coating obtained through implantation of titanium ions
Abstract
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.
