what is nanotech and their uses in future life?

Answer 1

Nanotechnology comprises technological developments on the nanometer scale, usually 0.1 to 100 nm. (One nanometer equals one thousandth of a micrometer or one millionth of a millimeter.) The term has sometimes been applied to microscopic technology

according to Smalley

Nanotechnology figures mightily in the practical harnessing of solar power—and, for that matter, in any long-term energy solution

"Nanotechnology is right at the core [of] the answer to the energy problem,"

In the case of solar power, for example, nanotechnology holds the promise of cutting the cost of photovoltaics by 10 to 100 times, he said. It may bring about a similar-scale reduction in the cost of fuel cells in enumerating two of "14 enabling nanotech revolutions" that could transform world energy production and usage.

These potential energy breakthroughs, which, he said, "could only come from nanotechnology," also include a "revolution" in hydrogen storage; direct conversion of light and water into hydrogen supplies; "photocatalytic" reduction of carbon dioxide; and nanomaterials, or coatings enabling the possibility of very deep drilling into Earth to obtain geothermal heat.

The best way to tap the sun's enormous energy stream may be to put solar power plants in space or on the moon, noting that solar cells in space could operate at about nine times the efficiency of similar cells on Earth.

"There [are] massive amounts of [solar] energy that miss the Earth every day," shooting right past it.

Here again, nanotechnology would figure critically: providing "super-strong, light-weight materials" that would make it possible to build efficient solar power-collecting space stations, and perhaps leading to nanoelectronics-based robots that could handle tasks such as maintaining space-based solar energy systems.

Answer 2

I will describe the answer in plain english. Nanotechnology is quite literally technology of the nano size; Nano is a term, just like micro and kilo, decribing the size of objects you are dealing with. In this case, at the molecular level. Using unique chemical, laser and electrical methods we are able to assemble individual atoms and/or molecules together for various purposes. This technology is emerging in just about every scientific field... everything from chemistry to medicine. It's an excting field because its seems to have a tremendous amount of applications, most of which we have not discovered or even thought of yet.
One exciting product is the nanotube. This is an assembly of atoms in a tube like shape. It is finding all sorts of uses... everthing from its use as an injecting apparatus to experimentations in quantum physics.
We have barely scratched the surface in this exciting field, but the fututre looks bright and full of suprises.

Answer 3

Nanotechnology is the design, characterization, production and application of structures, devices and systems by controlling shape and size at the nanoscale. Eight to 10 atoms span one nanometer (nm). The human hair is approximately 70,000 to 80,000 nm thick

Nanotechnology should really be called “nanotechnologies”: There is no single field of nanotechnology. The term broadly refers to such fields as biology, physics or chemistry, any scientific field, or a combination thereof, that deals with the deliberate and controlled manufacturing of nanostructures.The United States' National Nanotechnology Initiative website defines it as follows: "Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications."

Answer 4

Nanotechnology is the creation and manipulation of things on the nanometer scale, which refers to billionths of a meter. Nanotechnology has the potential for many things. For instance, one of the logical possibilities is miniaturization... computer chips could be made smaller and more powerful. In addition, nanoparticles are used in a wide variety of materials to increase physical properties like hardness, abrasion resistance, and the like. There is even the potential of using it to specially deliver drugs to specific cells in the body. In all, the range of potential uses is limited only by imagination.

Answer 5

well, these tiny objects will be put into a body, the blood vessels, that is. they will travel that "highway" & discover problems in the body, transmit that info' so it can be treated. the advantage is finding the problems early for early treatment.

Answer 6

how about little robots injected in your body, fixing cholesterol and killing cancer cells?
