摘要

Nanotechnology is a field of applied science that is concerned with the production, manipulation and use of materials at or close to the atomic and molecular levels. A common feature of nanotechnology is that it deals with structures that have features with sizes of 100nm or smaller, and it involves the development of materials and devices within that size range. In recent years there has been a surge of interest in nanotechnology as it has become clear that by operating much closer to the molecular level, it is possible to achieve things that are not possible on a coarser scale. Materials can show markedly different properties and the ability to operate at the nanometre level opens up new possibilities for a wide range of devices and applications across many industrial sectors.
