Nanotechnology -What is it?

Nanotechnology is a field of applied science and technology .This technology is concerned with the control of matter on a scale smaller than 1 micrometer, generally  between 1-100 nanometers, as well as the production of devices on this same length scale. The term "nanotechnology" was defined by Tokyo Science University Professor Norio Taniguchi in a 1974 paper as follows:

Definition of Nano Technology:"'Nano-technology' mainly consists of the processing of, separation, consolidation, and deformation of materials by one atom or one molecule." A imporatant concept of nanotechnology is the largely increased ratio of surface area to volume present in many nanoscale materials.

Applications include titanium dioxide and zinc oxide nanoparticles in sunscreen, cosmetics, silver nanoparticles in food packaging, clothing, disinfectants and household appliances, surface coatings and paints.
