Nanotechnology is the control and manipulation of matter at molecular and atomic levels. Drawing on advances in disciplines such as physics, chemistry, biology and computer science, nanotechnology creates and uses molecular particles, devices and composites that have special properties due to their extremely small size. These novel structures can display new phenomena not seen in the non-nano counterparts. This nanoscale matter can have a variety of possible applications--from creating superior cosmetics, paints and lubricants to detecting and treating diseases and generating energy.

To gain a greater appreciation of the scale of matter involved in nanotechnology, a strand of human hair is approximately 75,000 nanometres wide. Nanotechnology usually deals with the research and development of molecular particles, devices and composites roughly between 1 and 100 nanometres.You can use this online window to access additional information on nanotechnology such as:
