Construction and Antibacterial Properties of PhotoThermal Sterilization and Antifouling Surface

The adhesion of bacteria on the surface of materials is one of the biggest limitations for the long-term use of many medical implant devices. The adhesion of bacteria and other microorganisms on the surface of implanted biomaterials will form biofilm, which will cause infection to patients and bring great pain to patients. Therefore, it is of great significance to design coatings with dual functions of antibacterial and antifouling. In this paper, the photothermal sterilization effect of gold nanorods (AuNRs) and the antifouling characteristics of fluorine compounds are combined to prepare a surface material with sterilization antifouling at the same time, which solves the problem that it is difficult to remove dead bacteria on the surface of sterilization materials, resulting in the decline of sterilization performance.
