Nanotechnologies and nanosciences are the design, manufacture and manipulation of structures, devices and hardware systems at a scale of less than about forty nanometres.
Nanosciences and nanotechnologies are at the crossroads of several scientific disciplines such as electronics, mechanical engineering, chemistry, optics, biology handling objects of a size of the order of nanometres.
One of the major objectives of nanotechnology is to create nanomachines.
