Safety and Toxicity: The toxicity of nanomaterials can differ from their larger-scale counterparts. The small size can lead to increased reactivity and potential for unexpected biological interactions. Environmental Impact: The long-term environmental impact of nanomaterials is still under investigation. Concerns include the potential for bioaccumulation and the effects on ecosystems. Standardization: The lack of standardized methods for characterizing and measuring nanomaterials complicates regulatory processes. Uniform guidelines are necessary to ensure consistency across evaluations. Ethical Considerations: Ethical issues, such as privacy concerns with nanoscale sensors and the potential for dual-use technologies, need to be addressed. Public Perception: Public understanding and acceptance of nanotechnology are crucial. Clear, transparent communication regarding benefits and risks is essential to avoid misinformation.
