ECE- “C”

The study of the controlling of matter on an atomic and molecular scale. Generally nanotechnology deals with structures sized between 1 to 100 nanometer in at least one dimension, and involves developing or modifying materials or devices within that size.

CHALLENGES

They are a few challenges posed by nano-technology:

•too small for direct measurements

•too large to be described by current rigorous first principle theoretical and computational methods

•exhibit too many fluctuations to be treated monolithically in time and space

•too few to be described by a statistical ensemble.

CONCLUSION

Thus there is no doubt that nano-technology is a fast developing new technology that will revolutionarize the world in next few decades.There is a lot of R&D work going on in this field,giving us improvised products in many fields . Thus Nano technology also has a huge economical impact.For e.g. The US investment in nano-technology represents about ¼ of the world R&D investment.
