TiO2 nanoparticles have been investigated for use in targeted drug delivery systems. Their small size and high surface area make them suitable for encapsulating and transporting drugs to specific locations in the body.
Diagnostic Imaging:
Titanium dioxide nanoparticles are also being explored as contrast agents for medical imaging, including MRI and X-ray, due to their ability to enhance image clarity and resolution.

Safety and Handling

Health Considerations:
Titanium dioxide is generally considered safe for use in a wide range of applications, including cosmetics and food products. However, as with all nanopowders, it is important to handle TiO2 with caution to avoid inhalation or skin contact, which may lead to irritation or other adverse effects. Proper protective equipment, such as gloves and masks, should be used during handling.
Environmental Impact:
TiO2 is considered to have low environmental impact, as it is non-toxic and does not accumulate in the environment. However, further studies are being conducted to assess the long-term impact of nanomaterials on ecosystems, particularly in aquatic environments.
