In order to contribute with experimental evidence that could help to achieve a better understanding of the field for future regulation, in the present work, the biocompatibility of commercial P25TiO2NPs (one type of TiO2NPs used in sunscreen formulations) and two novel functionalized P25TiO2NPs were evaluated under solar simulated irradiation. White light, generated by red, blue, and yellow LEDs, together with UV ones, was chosen to simulate the solar spectra. Functionalization of TiO2NPs was made with antioxidant vitamins in order to prevent the expected photo-initiated ROS production when nanoparticles are exposed to the simulated solar spectra. Vitamin B2 (riboflavin) and vitamin C were chosen to carry out the functionalization because they are water-soluble, low-cost, and are a constitutive part of biological processes. In addition, it is known that both have the potential to prevent macromolecular oxidation by ROS [23][24][25][26].

The unique properties of titanium dioxide extend into the field of medicine as well. It is being researched for use in cancer treatment due to its ability to generate reactive oxygen species that can target and destroy cancer cells. Moreover, when used as a coating on medical implants, titanium dioxide helps prevent bacterial growth and promotes osseointegration Moreover, when used as a coating on medical implants, titanium dioxide helps prevent bacterial growth and promotes osseointegration Moreover, when used as a coating on medical implants, titanium dioxide helps prevent bacterial growth and promotes osseointegration Moreover, when used as a coating on medical implants, titanium dioxide helps prevent bacterial growth and promotes osseointegrationjual titanium dioxide.
