Nanotechnology-what it is!

Tweet

Nanotechnology is a field of applied science and technology covering a broad range of topics. The main unifying theme is the control of matter on a scale smaller than one micrometer, as well as the fabrication of devices on this same length scale.It is a highly multidisciplinary field, drawing from fields such as colloidal science, device physics, and supramolecular chemistry. Much speculation exists as to what new science and technology might result from these lines of research.Some view nanotechnology as a marketing term that describes pre-existing lines of research applied to the sub-micron size scale.
