nanotechnology

[-teknol′əjē]
technology at the level of atoms, molecules, and molecular fragments, including manipulating them and creating new structures.

nanotechnology

(nă″nō-tĕk-nŏl′ŏ-jē) [L. nanus, dwarf, + Gr. technē, art, + logos, word, reason]
The scientific study and engineering of chemical or biological objects measuring between 1 and 1000 nanometers. Objects this small are about the size of atoms or small molecules. “Wet” nanotechnology is the manipulation of organic or biological compounds in solution. “Dry” nanotechnology is the engineering of objects on silicon or carbon surfaces, such as those used in computing.

nanotechnology

The application of the science of manipulation at an atomic level. The practical applications of the ability to move single atoms so as to construct molecules, materials, structures and even functioning machines at an atomic level. Nanotechnology is currently at a germinal stage but is expected to have extensive applications in medicine. See also MAGNETIC NANOPARTICLES.
