Antibacterial properties of Cu-doped TiO₂ prepared by chemical and heat treatment of Ti metal

In this study, we proposed Cu-doped TiO2, prepared by the alkaline and heat treatment of titanium (Ti) metal, for use in dental applications because its bone-bonding antibacterial properties generated release Cu ions visible-light-responsive photocatalysis. We successfully TiO2 on a Ti chip surface with content 7 at.%. The apatite-forming ability was evaluated using simulated body fluid it found that apatite formation occurred. Hence, concluded exhibits properties. Escherichia coli were higher than those non-doped under visible light irradiation. enhanced effect mainly caused photocatalysis TiO2. confirmed reactive oxygen species hydroxyl radicals formed reaction hydroxide (OH−) holes (h+). Our findings are useful development novel bioactive TiO2-based coatings bulk materials doping.
