    It’s a prefix and it depends on the suffix it’s attached to. If you are talking about a nanometer it’s 10^-9 meters. If you are talking about nanotechnology, that’s a buzzward. In between that though there is plenty of meaning. If you are talking about graphene nanosheets, that means they are nanometers thick, i.e. roughly between 10^-9 m and 10^-7 m. In the material science context nano means the size of an object. Nanobeads would be nanometers in diameter. as opposed to microbeads which would be micron sized. A nanomachine would be a machine that is nanometers in size, etc.
