- Environment: Being very small these particles can create environment pollution
- Security: nano particles can be used in devices to capture videos or use as drones to launch offensive attack
- Equity: developing countries have less access to funds to create nanotechnology products
- Ethical:Using nano technology and devices in human beings can create a more powerful human being with enhanced human capabilities..should we pursue them?
- Technical barriers
Issues in India
- No single regulatory body in INDIA
- Insufficient studies on toxicological studies of nanoparticles
- Facilities required for research are less and outdates
