Visible light-induced controlled release and biological evaluation of bismuth sulfide quantum dots and silver nanoparticles co-sensitized titanium dioxide nanotubes.

ABSTRACT: Controlled drug delivery has attracted significant attention because of its ability to release therapeutic agents at specific times and locations. Titanium dioxide nanotubes (TNTs), which are known for their unique tubular morphology, large surface area and excellent biocompatibility, have been widely investigated as drug carriers. However, their application in light-induced drug release is limited by their reliance on ultraviolet (UV) light. In this study, bismuth sulfide quantum dots (Bi₂S₃ QDs) and silver nanoparticles (Ag NPs) were used to co-sensitize TNTs, increasing their light absorption in the visible spectrum and effectively reducing the recombination of photogenerated carriers. The methylene blue (MB) degradation of the 1Bi₂S₃-4Ag@U-TN
