Nanotechnologies are based on phenomena typically occurring on a scale of nanometres (see nanoscopic scale). The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.06 nm, and that of a ribosome is about 20 nm. The nanometre is also commonly used to specify the wavelength of electromagnetic radiation near the visible part of the s… Nettet0.1 nm. An atom is one of the basic units of matter.
