Definition of nanotechnology:-(Latest)

The technology devoted for the development and practical applications of structures & devices on an atomic scale that measure features less than 100 nanometers in size(i.e. one billionth of a meter) is called 'nanotechnology'. Which also refers to projected ability to construct items from the 'top-down' & 'bottom- up' using the techniques to make complete high performance products, like aerosols, colloids, polymers, bio-devices, targeted drugs, 3D transistors & networking, amplifiers actuators, robotics revolutionery and atomic design etc.
