will u tell me what is nanotechnology?

Question

i am an electrical engineer by profession.i dont know anything about nano technology.in what way it can help in my profession?

Answer 1

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 micrometre, 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.

Despite the apparent simplicity of this definition, nanotechnology actually encompasses diverse lines of inquiry. Nanotechnology cuts across many disciplines, including colloidal science, chemistry, applied physics, biology. It could variously be seen as an extension of existing sciences into the nanoscale, or as a recasting of existing sciences using a newer, more modern term. Two main approaches are used in nanotechnology: one is a "bottom-up" approach where materials and devices are built from molecular components which assemble themselves chemically using principles of molecular recognition; the other being a "top-down" approach where nano-objects are constructed from larger entities without atomic-level control.

Answer 2

Nano is Greek for dwarf, and nanoscience deals with the study of molecular and atomic particles, a world that is measured in nanometers (billionths of a meter or 10-9 ).

Nanotechnology research has focused primarily on molecular manufacturing -- the creation of tools, materials, and machines that will eventually enable us "to snap together the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of physics." A leading nanotech scientist describes past efforts at molecular level manufacturing as attempts to assemble LEGO pieces while wearing boxing gloves. Nanotechnology, he believes, will enable us to take off the gloves and build extraordinary things.

We are still in the dawn age of nanotechnology. Theories and techniques continue to emerge -- captivating scientists, students, entrepreneurs, investors, and even the U.S. government, which is betting that nanotechnology could lead to the next industrial revolution.

With powerful tools like the scanning tunneling microscope (STM), processes like molecular beam epitaxy (a way to build layered materials by "spray painting with atoms"), and brave new materials like fullerenes, the potential for innovation is vast. Nanotechnology is a realm of possibility that reads like speculative science fiction.

Answer 3

ok u neo what nano is rite nano are things that are smaller than usual something so small u ant even see ....nanotechnology is a setion in IT where they make technology like virus destroyer using something so small that u cant even see
here is a gud site to solve each and every one of ur problems based on something nano
