A well-done brief overview of molecular nanotechnology by University of Georgia chemist Dennis Rouvray is available at chembytes: "[Most] scientists were persuaded that nanotechnology was an unobtainable objective. Indeed, it was not until the second half of the 20th century that a few intrepid individuals risked raising their head above the parapet to question entrenched authority on the subject…Even with our current rudimentary chemical nanotechnology, it has been possible to fabricate a surprising range of simple nanomachines. These include abacuses, batteries, brakes, gears, plugs, rotors, ratchets, sensors, shuttles, sockets, switches and wires."
