Synergistic antibacterial photocatalytic and photothermal properties over bowl-shaped TiO₂ nanostructures on Ti-19Zr-10Nb-1Fe alloy.

ABSTRACT: As implant substitutes are increasingly applied to the clinic, the infection caused by implants has become one of the most common complications, and the modification of the antibacterial function of the implant can reduce such complications. In this work, a well-defined bowl-shaped nanostructure coating with photocatalytic and photothermal synergistic antibacterial properties was prepared on Ti-19Zr-10Nb-1Fe (TZNF) alloy. The coating is obtained by spin-coating and sintering TiO₂ precursors templated from self-assembled microspheres of polystyrene-poly(4-vinylpyridine) (PS-P4VP) amphiphilic block polymer on TZNF alloy. PS-P4VP provides the bowl-shaped TiO₂ nanostructures doped with C, N elements, reducing the band-gap of TiO₂, which can absorb near-infrared
