We have all witnessed that length scale has dropped from millimeters in 1950s to present day atomic scale. We have all seen benefits of Nanotechnology in miniaturization of microprocessors. Big mainframe computers have now been replaced with small PCs with IC chips. Medical profession has been the greatest beneficiary. This profession now has well developed technologies and equipment courtesy of Nanotechnology. With such advanced and precise instruments, doctors can invade deep in to human bodies and perform surgical operations with very little cuts leading to faster recoveries.
Nano-medicine in fact is a new term which has been coined to research and focus on the applications of this field in to medicine. Another area where the coming times will see a great breakthrough is development of cheaper solar cells. Presently solar technology has not become competitive because of prohibitive costs of Solar cells. Nano-science is expected to change the dynamics of solar cells market and lead to development of cheaper solar cells. Defense is another area which has reaped benefits of nano-science. Certain fabrics have been developed which are wrinkle free and can withstand the biological and chemical warfare with utmost ease.
Nanotechnology is going to be a major tool in universe’s fight with global warming. In India, there are several reputed institutes which have been offering postgraduate courses in Nano-science and nano technology. IITs and NITs are the major centers. In addition Amity and some private engineering colleges are also offering this course. Watch out for this career option. Nanotechnology is going to be a very popular course in the times to come.
