Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter.
Nanotechnology is the understanding and control of matter at the nanoscale, at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications.
Nanotechnology, the manipulation and manufacture of materials and devices on the scale of atoms or small groups of atoms. The ’nanoscale’ is typically measured in nanometers, or billionths of a meter (nanos, the Greek word for ’dwarf,’ being the source of the prefix).
Nanotechnology is the understanding, manipulation and control of matter at the nanoscale — at size ranges of about 1 to 100 nanometers — to produce new structures, materials and devices.
