Nanomedicine

This is the unit of measure used to describe things on an atomic scale. .
             Nanotechnology involves building things atom by atom on this atomic scale. This basic description may itself sound initially uninspiring, but the far-reaching and life-changing implications of this simple idea are infinite and truly mindboggling. .
             Nanotechnology will allow us to:.
            
             • Move individual atoms around at will. .
            
             • Build virtually any conceivable structure that is not outside the basic laws of physics. .
            
             • Have manufacturing costs not greatly exceeding the cost of the required raw materials and energy. .
             When nano-scale machines move from their present state of laboratory model and computer simulation to real-world application, human existence will undergo such radical and profound changes as to make us all but a completely new creature, in an utterly brand new world. .
             When did it all begin?.
             Broadly speaking, the central thesis of nanotechnology is that almost any chemically stable structure that can be specified can in fact be built. This possibility was first advanced by Richard Feynman in 1959 when he said: .
             "The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom." Feynman later won the 1965 Nobel prize in physics. .
             This concept is receiving increasing attention in the research community. There have been numerous international conferences directly on molecular nanotechnology as well as a recent report to US Congress on the state of the technology. .
             Science said "The ability to design and manufacture devices that are only tens or hundreds of atoms across promises rich rewards in electronics, catalysis, and materials. The scientific rewards should be just as great, as researchers approach an ultimate level of control - assembling matter one atom at a time." .
             Continuing: "Within the decade, John Foster at IBM Almaden or some other scientist is likely to learn how to piece together atoms and molecules one at a time using the STM [Scanning Tunnelling Microscope].
