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].

Anatase, known for its excellent photocatalytic activity, is primarily used in the production of advanced materials and environmental protection products. Its unique ability to break down pollutants under sunlight makes it an ideal choice for air purification and self-cleaning surfaces. On the other hand, Rutile, with its superior opacity and durability, is more commonly used in the coatings, plastics, and paper industries, providing a white pigment and UV protection.

For a mini-review published in the journal Particle and Fibre Technology in 2021, scientists wanted to evaluate whether Ti02 particles contributed to the development and/or exacerbation of irritable bowel disease, and whether they altered the four elements of intestinal barrier function: the intestinal microbiota, the immune system, the mucus layer, and the epithelium. The breakdown of these four elements can contribute to autoimmune, neurological, inflammatory, infectious, and metabolic diseases. Following their review, the researchers concluded: “Data indicate that TiO2 is able to alter the four compartments of IBF and to induce a low-grade intestinal inflammation associated or not with pre-neoplastic lesions.”

In the paint and coating industry, barium sulfate's superfine particles provide opacity, gloss, and improved flow characteristics. Its non-toxicity also makes it a safe option for use in paints designed for children's toys and other products where safety is paramount Its non-toxicity also makes it a safe option for use in paints designed for children's toys and other products where safety is paramount Its non-toxicity also makes it a safe option for use in paints designed for children's toys and other products where safety is paramount Its non-toxicity also makes it a safe option for use in paints designed for children's toys and other products where safety is paramountcheap barium sulphate superfine. In the plastics and rubber industries, it acts as a reinforcing agent, boosting mechanical strength and thermal stability without significantly affecting the overall cost.
