Imagine a supercomputer no bigger than a human cell. Imagine a four-person, surface-to-orbit spacecraft no larger or more expensive than the family car. Imagine attaining immortality by drinking a medicine. These are just a few products expected from Nanotechnology.
Nanotechnology is molecular manufacturing or, more simply, building things one atom or molecule at a time with programmed nanoscopic robot arms; Nanotechnology proposes the construction of novel molecular devices possessing extraordinary properties. The trick is to manipulate atoms Individually and place them exactly where needed to produce the desired Structure.
The goal of early nanotechnology is to produce the first nano-sized robot Arm capable of manipulating atoms and molecules into a useful product or Copies of itself. Nanotechnology will arrive with the development of the first "Universal Assembler" that has the ability to build with single atoms anything one's software defines. This paper deals with the various possible applications of nanotechnology and the process involved.
