China has emerged as a pivotal player in the global titanium dioxide industry, with its importers playing a crucial role in shaping the dynamics of this sector. Titanium dioxide, also known as TiO2, is a white pigment widely used in various applications such as paints, plastics, paper, and cosmetics. The country's growing demand for this versatile compound has led to an increase in import activities, making Chinese importers a vital link between domestic consumers and international producers.

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].
