For decades, implant-associated infections (IAIs) caused by pathogenic bacteria have been associated with high failure and mortality rates in implantation surgeries, posing a serious threat to global public health. Therefore, developing a functionalized biomaterial coating with anti-fouling and anti-bacterial functions is crucial for alleviating implant infections. Herein, a near-infrared-responsive anti-bacterial and anti-adhesive coating (Ti-PEG-CuS) constructed on the surface of titanium (Ti) implants is reported. This coating is composed of nano-CuS with anti-bacterial activity and super-hydrophilic polyethylene glycol (PEG). Under near-infrared irradiation, the nano-catalyst CuS on the surface of Ti-PEG-CuS induces bacterial death by catalyzing the production of singlet oxygen (O). The Ti-PEG-CuS coating can effectively prevent bacterial adhesion and biofilm formation. This coating combines the antibacterial mechanisms of "active attack" and "passive defense", which can kill bacteria and inhibit biofilm formation. The results of and experiments have shown that Ti-PEG-CuS exhibits excellent anti-bacterial properties under near-infrared irradiation and can effectively prevent implant-related infections caused by () ATCC 8739 and (). The antibacterial efficiency of Ti-PEG-CuS coatings against was 99.96% ± 0.058% and that of was 99.66% ± 0.26%, respectively. In addition, the Ti-PEG-CuS coating has good blood compatibility and excellent bactericidal ability. Therefore, this multifunctional coating combines a non-adhesive surface strategy and a near-infrared phototherapy sterilization method, effectively blocking the initial attachment and proliferation of bacteria on implants photothermal/photodynamic effects and providing a promising method for preventing bacterium-induced IAIs.
