Nano Machines

[ahlam1399]

Nano machines are devices that range in size from the smallest of MEMS devices down to devices assembled from individual molecules. This section briefly introduces energy sources, structural hierarchy, and the projected future of the assembly of nano machines. Built from molecular components performing individual mechanical functions, the candidates for energy sources to actuate nano machines are limited to those that act on a molecular scale. Regarding manufacture, the assembly of nano machines is by nature a one-molecule-at-a-time operation.
