One of the most notable characteristics of mixed crystal nano titania is its ability to absorb light across a wide range of wavelengths. This property makes it an excellent photocatalyst, capable of driving chemical reactions using only sunlight as the energy source. As such, it has found use in environmental remediation efforts, where it can help break down pollutants and harmful chemicals in water and air. Additionally, its high surface area-to-volume ratio allows for efficient adsorption of gases and liquids, making it useful in sensors and filters.

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].
