However, nanotechnology also raises concerns about the potential risks and challenges associated with its development and use, including:

1. Environmental and health risks: The potential for nanoparticles to harm humans, animals, and the environment is a major concern.
2. Regulation and governance: The lack of clear regulations and guidelines for the development and use of nanotechnology is a challenge.
3. Public awareness and education: The public needs to be educated about the benefits and risks of nanotechnology to ensure informed decision-making.
