  2. Definition • A nanomachine, also called a nanite, is a mechanical or electromechanical device whose dimensions are measured in nanometers (millionths of a millimeter, or units of 10-9 meter). This is a representation of a nanomachine. The colored balls represent individual atoms that comprise the machine.

  3. Visionary • During the 1980’s and 1990’s, K. Eric Drexler popularized the potential for nanomachines.. • The ultimate goal of nanomachine technology is to build an “assembler” nanomachine that is designed to manipulate matter at the atomic level. • The “assembler” would be able to rearrange atoms from raw materials in order to produce useful items.

  4. Engineering • The most important challenge to overcome is one of molecular engineering. Rearranging atoms into new shapes is essentially building new molecules. • Through experimentation, more control could be gained on how molecules are formed. • In time, chemists will be able to position individual atoms by techniques developed in chemical synthesis. In computer simulations, molecularly stable gears and cogs have been formed through chemical synthesis. Nanogear
