Nanotechnology

Nanotechnology

is the manipulation of matter one atom or molecule at a time to make tiny structures or tools with one or more dimensions between one and 100 nanometers (a billionth of a meter). Many “nanotech” devices are made of new materials and some self-assemble. Some use conventional (Newtonian) physics and quantum mechanics, where physical properties can change in unexpected ways. Nanotech applications include biology and medicine, electronics, mechanics, photonics, and ion transport.
