Abstract

Increasing osteoporosis-related fractures caused by the increasing aging population and orthopedic diseases have been bringing about booming demand for artificial implant materials[1,2]. However, the surface of these artificial implants often provides an hospitable place from bacterial attachment and growth after implantation in vivo. Once bacterial biofilm forms on the surface, it has to remove these implants through second surgery because it is very difficult to treat it by antibiotics[3-5]. Herein, we for the first time to endow the implant materials (biomedical titanium implant material) with excellent antibacterial ability of through inspiring both photocatalytic and photothermal properties of CS/MoS₂ hybrid coating by short-term dual lights irradiation simultaneously.
