Abstract

Exposure to ultraviolet (UV) radiation induces many serious health issues. Because of serious health concerns, there is an urgent need to develop UV filters with better efficacy and high safety. For this purpose, titanium dioxide (TiO₂) nanoparticles are the most desirable materials due to their excellent UV protection abilities. The use of TiO₂ as sunscreens has raised some concerns about potential risks due to the formation of TiO₂-mediated free radicals. Herein, TiO₂ nanoparticles have been successfully embedded in silica (SiO₂) microspheres using the emulsion synthesis method. The as-synthesized TiO₂ nanoparticles embedded in silica microspheres have shown excellent UV protection ability. TiO₂ nanoparticles embedded in silica microspheres suppress the photocatalytic properties compared to bare TiO₂ nanoparticles, and these results indicate that TiO₂-embedded silica microspheres are promising UV protection materials for sunscreen.
