Visible Light-Enhanced Antibacterial and Osteogenic Functionality of Au and Pt Nanoparticles Deposited on TiO2 Nanotubes

Abstract: This study aimed at evaluating the visible light mediated antimicrobial and osteogenic applications of noble metal, such as gold (Au) and platinum (Pt) coated titania (TiO2) nanotubes (NTs). In this study, the Au and Pt nanoparticles (NPs) were deposited on anodized 100 nm TiO2 NTs by ion plasma sputtering. The Au and Pt NPs were mainly deposited on the top surface layer of TiO2 NTs and showed light absorbance peaks around the 470 and 600 nm visible light region used in this study, as seen from the surface cha… Show more

“…In previous studies, we have developed Au and Pt single-coated TiO 2 nanotubes showing visible light photocatalytic activity and osteogenic acceleration with selective visible light irradiation [22][23][24]. This research also showed that the resulting species of noble metal nanoparticles affected the antibacterial activity and osteogenic performance and were the basis for further investigations into variable factors such as species, morphology, and the coating conditions of the noble metal nanoparticles.…”

“…The procedure, materials, and reagents for preparing anatase crystalline phased TiO 2 nanotubes with diameters of 100 nm are the same as our previous research [24]. The specimen for the anodization process was 5 × 5 cm 2 and was cut to the size of 1 × 1 cm 2 to perform noble metal coating and in vitro experiments.…”
