Nanomachines just won the Nobel Prize in Chemistry
If you want to know how far nanotechnology has come, you only need to ask the Royal Swedish Academy of Sciences. It just awarded the Nobel Prize in Chemistry to researchers Bernard Feringa, Jean-Pierre Sauvage and Sir J. Fraser Stoddart for their work on the "design and synthesis of molecular machines." All three have been instrumental to making nanomachines possible. Sauvage kicked things off in 1983, when he linked ring-shaped through a mechanical bond instead of the usual electron-sharing bond. Stoddart carried the torch when he slipped a moving molecular ring on to an axle in 1991, while Feringa built the first molecular motor in 1999.
