One of the primary functions of titanium dioxide in plastic manufacturing is its ability to act as a potent ultraviolet (UV) light absorber. By incorporating TiO2 into plastic formulations, manufacturers can create materials that resist discoloration and degradation caused by exposure to sunlight and other sources of UV radiation. This not only extends the lifespan of the final product but also maintains its aesthetic appeal over time, making it especially valuable for outdoor applications such as gardening tools, outdoor furniture, and automotive parts.

The vitaminC@P25TiO2NPs, on the other side, did not have any effect on cell protection against ROS. This might be due to the fact that vitamin C, a well-known scavenger of ROS, could behave as prooxidant and even promote ROS and lipid peroxidation [39]. It was recently described that at small concentrations of vitamin C, the prooxidant effects dominate; while in large concentrations the antioxidant ones predominate [40]. The effect also depends on the cell state and the interaction of vitamin C with light. In this case, ascorbic acid may act as an antenna to harvest visible light when conjugated to P25TiO2NPs. Indeed, it was previously found that this combination (in some ratios) could have an improved photocatalytic activity, possibly due to a red shift in its light absorbance [41]. Further studies on vitaminC@P25TiO2NPs were not conducted, because of the poor antioxidant capacity [42].
