What are the Challenges and Risks Associated with TiO2 Nanoparticles?
Despite the benefits, there are several challenges and risks associated with the use of TiO2 nanoparticles:
Toxicity: The potential health risks and environmental impact of TiO2 nanoparticles are not fully understood. Studies are ongoing to assess their long-term effects on human health and ecosystems. Aggregation: TiO2 nanoparticles tend to aggregate, which can reduce their effectiveness. Researchers are working on surface modifications to prevent this aggregation. Regulation: The regulatory landscape for nanomaterials is still evolving, and there is a need for standardized guidelines to ensure safe use and disposal of TiO2 nanoparticles.
