how much scope does nanotechnology have?

Answer 1

Immense, it will dominate all future technologies.

Answer 2

Nanotechnology will affect every aspect of our life from computer science to medicine. Most of the developments being done today are in the material science area, as a result this new enhanced materials will have applications in a broad range of areas.

According with a study done by the CPGGH (Canadian Program on Genomics & Global Health), the top 10 nanotechnology applications most likely to have an impact in the developing world in the next 10 years are:

- Energy storage, production and conversion.
- Agricultural productivity enhancement.
- Water treatment and remediation.
- Disease diagnosis and screening.
- Drug delivery systems.
- Food processing and storage.
- Air pollution and remediation.
- Construction.
- Health monitoring.
- Vector and pest detection and control.

More areas where nanotechnology will be used are:
transportation, aerospace applications and nanomanufacturing.

As usual, new technologies have positive aspects as well as negative aspects. Some negative applications would be in the areas of:
- Security: Biological & chemical warfare, manufacturing new viruses, nanoterrorism.
- Privacy: Bank records stolen with fast computers, nanoscale as powerful spy tools.
- Health: Toxicity of nanoparticles for environment & our body.
- Raise Ethical Issues: Patent Protection, Public Health, Equity.

Answer 3

There is potential for use in several fields, but there are human health concerns related to accidental release of nanoparticles into breathable air. Environmental regulations may influence proliferation of this technology.
