CONCLUSION

The word ‘nano’ means dwarf or little old man.

It indicates extreme smallness.

Means one-billionth of……….a meter, litre, gram etc.

Definition:-

Research and technology development at the atomic, molecular or macromolecular levels in the length scale of 1-100 nanometer range(approx).

Algae and barnacles couldn’t cling to the nano-coating.

Better surface appearance. Optical clarity. Easy to clean surface. Good chemical resistance.

Health risks Medical application of nanoparticles

ex: enhance drug delivery

Some nanoparticles —freely mobile Negative health and environmental impacts

Nano-particle is “EVERYWHERE”.

Huge impact in research world.

Expected to have an impact on

Every industry.
