What is nanotechnology? Nanotechnology is a rapidly developing field that deals with the manipulation of matter on an atomic and molecular scale, typically ranging from 1 to 100 nanometers (nm). This realm is incredibly small, as a comparison – a human hair is roughly 80,000 nm wide! By working at this tiny scale, scientists can create materials and devices with unique properties that wouldn’t be possible using traditional methods.
