Nanotechnology and Nanobots!

Robots at the cellular level, what will they think of next?

Are there doomsday implications with nanotechnology?  But first, what is nanotechnology?  In recent general usage, any technology related to features of nanometer scale: thin films, fine particles, chemical synthesis, advanced microlithography, and so forth. A technology based on the ability to build structures to complex, atomic specifications by means of mechanosynthesis; this can be termed molecular nanotechnology.
