  • 2. DefinitionA nanomachine, alsocalled a nanite, is amechanical orelectromechanicaldevice whosedimensions aremeasured innanometers(millionths of amillimeter, or units of10-9 meter).This is a representation of ananomachine. The colored ballsrepresent individual atoms thatcomprise the machine.
  • 3. VisionaryDuring the 1980’s and 1990’s, K.Eric Drexler popularized thepotential for nanomachines..The ultimate goal ofnanomachine technology is tobuild an “assembler”nanomachine that is designedto manipulate matter at theatomic level.The “assembler” would be ableto rearrange atoms from rawmaterials in order to produceuseful items.
  • 4. EngineeringThe most important challenge to overcome is one of molecularengineering. Rearranging atoms into new shapes is essentiallybuilding new molecules.Through experimentation, more control could be gained on howmolecules are formed.In time, chemists will be able to position individual atoms bytechniques developed in chemical synthesis.In computer simulations,molecularly stable gears and cogshave been formed throughchemical synthesis.Nanogear
