Ideas of modern nano-has been mentioned Richard Feynman in his famous lecture "There's a lot of space at the bottom" in 1959. Then he talked about the possibility of chemical manipulations at the atomic level, and suggested that when a patient is simply "swallow a surgical machine," which will come into place and everything patched. It took 50 years and scientists are still struggling with the creation of such a surgeon, but Feynman, no doubt, would have impressed the fact that we have done to date.Nanomedicine is firmly gaining a place in the field of drug delivery and diagnostics.
