Nanotechnology

There is no formal definition of nanotechnology, but in simple terms it is the understanding of the processing, properties and applications of materials or devices that are on the 'nano-scale' in at least one dimension. That generally means distances of less than l00nm. Since, atoms are typically separated by about 0.3 of a nanometer, this means arrangements of atoms of molecules that there are, typically, a few hundred atoms or less.
