What if you could fix all the damaged cells in your body and eliminate any infections or cancers? What if every cell in your body could be destroy? Nanotechnology has the possibility of doing all that in the future. This makes nanotechnology a truly powerful thing. The science of nanotechnology must first be understood, then, its advantages must be considered, and finally, its disadvantages need to be addressed.
In nanotechnology, machines are built on a microscopic scale of nanometers. Just as a millimeter is 1/1,000 of a meter, a nanometer is 1/1,000,000,000 of a meter. Scientific American states, "All living things come from strings of atoms. Assembling these atoms is how trees, humans, and other forms of life are born, grow, and live".
