User can create, shape and manipulate nanites, machines or robots whose components are at or near the scale of a nanometre. More specifically, nanorobotics (as opposed to microrobotics) refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1–10 micrometres and constructed of nanoscale or molecular components. This allows the use of nanotechnology: manipulation of matter on an atomic, molecular, and supramolecular scale.
