I predict a breakthrough in the next 5 years, with so many other technologies running full throttle in new developments there has to be a crossover that opens a new door for nanobot technology.

US researchers have built a proto-prototype nano assembler
The first real steps towards building a microscopic device that can construct nano machines have been taken by US researchers. Writing in the peer-reviewed publication, International Journal of Nanomanufacturing from Inderscience Publishers, researchers describe an early prototype for a nanoassembler.
In his 1986 book, The Engines of Creation, K Eric Drexler set down the long-term aim of nanotechnology – to create an assembler, a microscopic device, a robot, that could construct yet smaller devices from individual atoms and molecules. Read more
