We’ve been hearing about nanotechnology for a long time in both science fiction and in the media, but not much has come of it so far. However, a new wave of nanotech-based therapies are on the horizon, and are ready to change the world of medicine. Nanotechnology, a technological concept first proposed by Richard Feynman in his 1959 lecture, “There’s Plenty of Room at the Bottom”, was popularized by Erik Drexler in 1986 via his book “The Engines of Creation.” The book outlined the possibility of self-replicating, molecular-scale machines capable of doing… pretty much anything.
