In addition to the toxic effects of TiO2 NPs, discussed in previous chapters, these NPs have been also shown to promote photosynthesis and nitrogen metabolism, resulting in the enhanced growth of spinach. It increases the absorption of light and accelerates the transfer and transformation of the light energy. It was also found that treatment with nano-sized TiO2 significantly increased the level of antioxidant enzymes, and decreased the ROS accumulation and malonyldialdehyde content in spinach chloroplasts under visible and UV irradiation. TiO2 NPs also increased the superoxide dismutase activity of germinating soybean, enhanced its antioxidant ability, and promoted seed germination and seedling growth.

One of the most significant uses of titanium dioxide is in the production of paints and coatings. It acts as a pigment that provides brightness, opacity, and durability to the final product. The high refractive index of titanium dioxide allows it to scatter light effectively, making it ideal for creating opaque finishes. Moreover, its chemical stability ensures that the color remains consistent over time, even when exposed to harsh environmental conditions.
