Nano-scale technology is a suite of techniques used to manipulate matter at the scale of atoms and molecules. “Nano” is a measurement – not an object. Unlike “biotechnology,” where you know that bios (life) is being manipulated, “nanotechnology” speaks solely to scale. A “nanometre” (nm) equals one billionth of a metre. One human hair is about 80,000 nanometres thick. It takes ten atoms of hydrogen side-by-side to equal one nanometre. A DNA molecule is about 2.5 nm wide. A red blood cell is vast in comparison: about 5,000 nm in diameter. Everything on the nano-scale is invisible to the unaided eye and even to all but the most powerful microscopes.
