Nanowonders - Wonders of Nanotechnology

Article Image

Nanotechnology is the science and technology of small things that are less than 100nm in size. One nanometer is 10-9 meters or about 3 atoms long. Nano particles are in abundance in nature. the new thing about nanotechnology is that we can now control these structures and properties to make new functional materials and devices. We have entered the era of engineered nano materials and devices. Another interesting area of nanotechnology results from starting at the atomic scale and building up materials and structures , atom by atom. This molecular engineering is called molecular or chemical nanotechnology. The nano materials created this way have resulted in a number of consumer products like treated bed sheets, clothes, ceramic & glass coatings for cars, flash memory, ceramic hair straighteners, industrial coatings etc. These materials have unique properties because of their small size. Researchers are using these unique properties of materials at this small scale to create n
