Nanoengineering is the practice of engineering on the nanoscale. It derives its name from the nanometre, a unit of measurement equalling one billionth of a meter. Nanoengineering is largely a synonym for nanotechnology, but emphasizes the engineering rather than the pure science aspects of the field.

A nanotechnology engineer is someone who works around the smallest, most amazing fragments of science. From storing and altering things on the cellular level, to creating new, tiny pieces of electronics, nanotechnology engineers are the cream of the crop, possessing an acute attention to detail and a strong drive to make things better.
