Nanotechnology
Nanoscale science investigates the matter at the critical range on 1 - 100 nm (nano meter). Making new things on this incredibly small scale is called nanotechnology and it's one of the most exciting and fast-moving areas of science and technology today. Nanotechnology is an enabling technology which has applications in a diverse areas from biology to aerospace.
History of nanotechnology
Nanoscience and technology are not new concepts to the nature. There are many natural phenomena based on nanotechnology. However, the American physicist Richard Feynman (1918 - 1988) is credited with kick-starting modern interest in nanotechnology. In 1959, in his after-dinner speech called "There's plenty of room at the bottom, "Feynman speculated about an public speaking incredibly tiny world where people could use atoms and molecules as tools to make things. In 1974, Japanese engineering professor Norio Taniguchi named this field "nanotechnology".
Nanotechnology truly took off in the 1980s. That was when nanotech-evangelist Dr. K. Eric Drexler first published his groundbreaking book "Engines of Creation: The Coming Era of Nanotechnology". Nanotechnology could not really took off until the electron microscopy became popular. It was also the decade when microscopes that were capable of manipulating atoms and molecules on the nanoscale were discovered.
