  • Nanotechnology

    The ability to work at the atomic, molecular, and supramolecular levels, in a scale of about 1 to 100 nanometers, in order to create, manipulate and use materials, devices, and systems that have novel properties and functions because of the small scale of their structures. All materials and systems establish their foundation at nanoscale. A water molecule is about 1 nm in diameter, and the smallest transistors measure about 20nm. DNA molecules are about 2.5 nm wide, a typical protein between 1 and 20 nm in diameter.
