Nanotechnology. What is Nanotechnology? Short definition of Nanotechnology. Use of Nanotechnology.
Nanotechnology refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products. K. Eric Drexler popularised the world 'nanotechnology' in the 1980's, by talking about building machines on the scale of molecules, a few nanometers-wide motors, robot arms and even whole computers, far smaller than a cell. Nanotechnolgy, in its traditional sense, means building things from bottom up, with atomic precision. This theoretical capacity was envisined as early as 1959 by the renowned physicist Richard Feynman.
Four Generations
2000 1st. Passive Nanoconstructures
First generation products: (a) aerosols,colloids (b) coating, nanoparticles reinforced composites, polymers, ceramics, nanostructured metals, etc.
2005 Active Nanoconstructures
Second generation products: (a) bio-active like targeted drugs, bio-devices (b) Physico-chemical active - 3D transistors, actuators, etc. 2010 Nanosystems Third generation products: (a) guided asssembling, 3D networking, robotics 2015/20Molecular Nanosystems Fourth generation products: molecular devices, atomic design, etc.
