A radical nanotechnology concept pioneered by K.E. Drexler involving computer-controlled engineering and construction of nanoscale machines (including nanogears, nanosorters, nanomotors, nanofactories, and (nano)assemblers) to make macroscopic objects. Could be described as the principles of mechanical engineering applied to chemistry.
