What is Nanotechnology?
Abstract
Nanotechnology is defined as ”the design, characterization, production, and application of materials, devices, and systems by controlling shape and size at the nanoscale.” In other words, it is both a process, called nanofacture or ultraprecision engineering, and a class of materials. The nanoscale consensually means the range 1–100 nm; nanomaterials are structured and/or sized in this range. Nanotechnology is sometimes also called atomically precise engineering, but techniques processing single atoms in the manner of additive manufacturing with powders (called “productive nanosystems”) are still inchoate and do not yet constitute a universal manufacturing technology. Some nano-objects are used ...
