Photocatalytic Activity and Antibacterial Efficacy of UVA-Treated Titanium Oxides

摘要

All anodized surfaces showed accelerated MB degradation compared to CPTi. After 1 h of exposure, the mixed phase surface of C180 showed the greatest degradation. All surfaces reduced bacterial attachment to approximately the same amount of CFU, however, B156 and C180 promoted more initial bacterial attachment, which resulted in higher killing efficiency. Further research is ongoing on the bacterial efficacy of the anodized coatings against commonly acquired bacterial species to determine the susceptibility to titanium oxide PCA.
