Building biointegration of Fe₂O₃-FeOOH coated titanium implant by regulating NIR irradiation in an infected model.

ABSTRACT: Killing bacteria, eliminating biofilm and building soft tissue integration are very important for percutaneous implants which service in a complicated environment. In order to endow Ti implants with above abilities, multifunctional coatings consisted of Fe₂O₃-FeOOH nanograins as an outer layer and Zn doped microporous TiO₂ as an inner layer were fabricated by micro-arc oxidation, hydrothermal treatment and annealing treatment. The microstructures, physicochemical properties and photothermal response of the coatings were observed; their antibacterial efficiencies and cell response in vitro as well as biofilm elimination and soft tissue integration in vivo were evaluated. The results show that with the increased annealing temperature, coating mo
