Can anyone explain me about 'Nano technology' .?

Answer 1

Nano means small....

So in simple laymans language u can say that it deals with combining lots of large things into one............

for example.............
in an electronic circuit ,there are resistors ,capacitors,transisters...........
when all of them are combined to form one IC (integrated circuit)....we say that we have made use of nanotechnology...........

EXTRA KNOWLEDGE

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 1 micrometre, normally between 1-100 nanometers, 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.

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, materials science, and even mechanical and electrical engineering.

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.

The impetus for nanotechnology has stemmed from a renewed interest in colloidal science, coupled with a new generation of analytical tools such as the atomic force microscope (AFM), and the scanning tunneling microscope (STM). Combined with refined processes such as electron beam lithography and molecular beam epitaxy, these instruments allow the deliberate manipulation of nanostructures, and in turn led to the observation of novel phenomena. The manufacture of polymers based on molecular structure, or the design of computer chip layouts based on surface science are examples of nanotechnology in modern use. Despite the great promise of numerous nanotechnologies such as quantum dots and nanotubes, real applications that have moved out of the lab and into the marketplace have mainly utilized the advantages of colloidal nanoparticles in bulk form, such as suntan lotion, cosmetics, protective coatings, and stain resistant clothing.

Answer 2

nanotechnology(1 nano=10^-9 metres)

The science of developing materials at the atomic and molecular level in order to imbue them with special electrical and chemical properties. Nanotechnology, which deals with devices typically less than 100 nanometers in size, is expected to make a significant contribution to the fields of computer storage, semiconductors, biotechnology, manufacturing and energy.

Envisioned are all kinds of amazing products, including extraordinarily tiny computers that are very powerful, building materials that withstand earthquakes, advanced systems for drug delivery and custom-tailored pharmaceuticals as well as the elimination of invasive surgery, because repairs can be made from within the body.

Larry Bock, CEO of Nanosys, who helped launch more than a dozen successful biotech companies in his career, believes that nanotech will impact even more industries than biotech. In an excerpted article from the March 2003 Nanotech Report, he compared nanotechnology with the microelectronics industry. Bock said that "a single chemistry graduate student can create novel devices and device architectures not even imaginable or manufacturable by today's biggest microprocessor companies. That is because these devices are fabricated chemically, or from the bottom up. Existing microelectronics technology is fabricated by etching wafers, or from the top down." See AFM, STM, Buckyball, nanotube and MEMS.

Answer 3

Nanotechnology is the creation of functional materials, devices and systems through control of matter on the nanometer length scale (1-100 nanometers), and exploitation of novel phenomena and properties (physical, chemical, biological, mechanical, electrical...) at that length scale. For comparison, 10 nanometers is 1000 times smaller than the diameter of a human hair. A scientific and technical revolution has just begun based upon the ability to systematically organize and manipulate matter at nanoscale. Payoff is anticipated within the next 10-15 years.

Answer 5

basically little computer chips that are so small the human eye can not see them, or barely can see them. they can be used as implants or tracking devices, or for many other uses.
