what is nanotechnology?
103618
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.\n\nEnvisioned 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.\n\nLarry 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."\n\nBy 2020, scientists at Rutgers University believe that nano-sized robots will be injected into the bloodstream and administer a drug directly to an infected cell. This robot has a carbon nanotube body, a biomolecular motor that propels it and peptide limbs to orient itself. Because it is composed of biological elements such as DNA and proteins, it will be easily removed from the body. For more information, see http://bionano.rutgers.edu/Mavroidis_Final_Report.pdf.

I presume we are talking electronics here. Nano technology implies that circuits are of the order of nanometres(very very small). The problems with this is that as the tracks in an integrated circuit (IC) get closer together they interfer with each other through heat, magnetic field effect and electric field effects. The benefits are that because track lengths are small the wires between components do not have to be treated as transmission lines (complicated) at the very high frequencies we demand of modern electronics. \n\nIn sum it is more difficult but gives better results.

Nanotech is currently in existence, and being used commercially in special (and expensive) products such as memory cloth (capable of holding its shape when an electical current, such as bioelectromagnetic fields, passes through it. The normal looking synthetic cloth becomes strong and stiff as aluminium to a preprogrammed shape (exactly like what was seen in the hollywood blockbuster Batman Begins).\nTechnology in this area has limitless potential for growth, and as human understanding of the little pieces that make up everything improves, everything we use will become smaller and more useful. Are there littler pieces that make up the strings that Super String Theory has come to understand are the building blocks of thought and feeling? can those smaller pieces be used to control energy itself in order to literally control the fabric of existence? or make objects disappear into the space that makes up 99.9recurring percent of the size of matter? These things are well and truly feasable. Turning worthless metals into gold or diamond is ancient alchemical technology, developed and used over 4000 years ago. I think we can aim higher than that.\nIn the future, assembly lines will not be neccessary, as the nanobites will be programmed to repair, rebuild and replace themselves and each other, in-situ, as necessary, with the use of artificial intelligence programming.

Nanotechnology is a hybrid science combining engineering and chemistry. Atoms and molecules stick together because they have complementary shapes that lock together, or charges that attract. Just like with magnets, a positively charged atom will stick to a negatively charged atom. As millions of these atoms are pieced together by nanomachines, a specific product will begin to take shape. The goal of nanotechnology is to manipulate atoms individually and place them in a pattern to produce a desired structure. \n\nSome upcoming technology you might be interested in: Pervasive computing, mobile computing, biotechnology

Nanotechnology, currently, mostly has to do with materials science, via creating micro structures that can withstand extreme stresses in either longitudal (carbon nano-tubes) or rotational (bucky-balls) directions, and any connection to aerospace is merely a coincidental imagining of people who are dreaming up ways to use these new exotic materials for aerospace applications.  Nanotechnology, in essesnce, is 'building' materials (metals, plastics, polycarbonates) from the basic atomic/molecular structure up.\n\nCurrently the only applications that I have heard of are in relation to a surface to low earth orbit(LEO)'elevator' which would be used to hoist payloads from the surface to LEO.  This setup would be extremely fragile though and tend to break even with the current nano-materials available.  \n\nThe other area where it would be of interest and much more probably of use, is in the area of heat resistant applications such at heat shields for re-entering spacecraft.  Nano-materials can be engineered to be highly resistant to high temperatures without their material properties changing drastically.  This would be a far greater useablility than any sort of space elevator.

A nanometer is a unit of spatial measurement that is 10-9 meter, or one billionth of a meter. It is commonly used in nanotechnology, the building of extremely small machines.

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\n\naccording to Smalley\n\nNanotechnology figures mightily in the practical harnessing of solar power—and, for that matter, in any long-term energy solution \n\n"Nanotechnology is right at the core [of] the answer to the energy problem," \n\nIn 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.\n\nThese 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.\n\nThe 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.\n\n"There [are] massive amounts of [solar] energy that miss the Earth every day," shooting right past it.\n\nHere 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.

Nanotechnology is everywhere already, most people just don't know it. For nearly one hundred years US spies have been using miniature gadgets cleverly sealed within everyday things, popularized by the James Bond movies and other spy-thrillers.  The term nano is anything that we deem reallyreallyreally small. IE Ipod Nano, etc. I think by Nano you mean, REALLY small, and alot of things already are, like the phone and watch analogie you used, one of the best ways to keep in-touch with nanotechnology and to understand its direction, is to study its past and present first, try livescience.com or wikipedia.org, good luck!

The main research for nanotechnology is to make our current technology smaller and more efficent.  However, medical research will be one gigantic step. The innovations that nanotechnology can provide to medicle science is extreme, from minimizing the amount of surgery that is done, to venal and artirial repairs, to healing of wounds and stiching of cuts and fractures.  Some great resources on nanotechnology are listed in the 'sources' section below:

Nanotech is indeed real. Have you never seen surveillance cameras the size of a dime, and what about tracking devices about the size of a cigarette lighter?Do you remember how many different components use to be in a regular am radio & tv set? Tubes, capacitors, resistors, coils, etc. are now on a pc circuit board in the form of an integrated circuit about 1"x1/4". The first computer ever devised needed many rooms to house. The laptop now is less than the sise of some wire bound notebooks high school kids carry.

The term "nanotechnology" has evolved over the years via terminology drift to mean "anything smaller than microtechnology," such as nano powders, and other things that are nanoscale in size, but not referring to mechanisms that have been purposefully built from nanoscale components.\n\nPls go through following link...it will definately help you...\n\nhttp://www.nanotech-now.com/introduction.htm

Nanotechnology is a new technology just in its infancy and being researched in labs all over the world. In principle any device that is manufactured to a nano-meter or even micro-meter scale would be considered to be nanotechnology.\n\nAt the moment practical nanotechnology is limited to MEMs devices (micro-electromechanical systems). In the same way that you can etch and deposit onto a silicon wafer to create electric circuits, you can etch and deposit a bit more to make structures like micro-mirrors, cantilevers, micro-bridges and a whole host of other little things. Cantilevers for instance can be used to make very tiny accelerometers like the ones that initiate air bags in cars. Micro-mirrors will be used to make the next generation of visual displays after LCDs. There are many many more possible applications.\n\nYou can read more about this at www.memsstar.com
