(m)\n\nNanotechnology 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

Small clowns-jk\nA few areas will benefit\nPhysics will see some information on how physics works at such a small scale\n\nMedicine(in the future)- These nano cars could be the model that future nano-bots can be based off of to repair cells at a atomic level, or alter other things in the body like protein production.  kind of like a built in gene therapy. Or deliver drugs when needed\n\nelectronics- I am going out on a limb here but I could say self repairing computers

Nano technology is the latest buzz which have tremendous scope in coming future because we are going towards slimmer gadgets with greater features and nano technology is the only solution which can make this happen.\n\nGood luck

There are still issues on nanomanufacturing.  If you want to know, nano-electronics are made from nanotransistors.  These nanotransistors are made from carbon nanotubes - they look like sot after a chimney sweep.\n\nThere are already companies involved in nanotechnology.  A few of them are in Massachusetts.  I believe the new generation of optical electronics will have nanotechnology - probably around 2008.

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

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 engineering that deals with the study of molecular and atomic particles, measured in nanometers (billionths of a meter or 10 to the-9 ).

Nanotechnology is the science of fooling around with materials, albeit at the atomic scale. In their constant endeavor at trying to understand the behavior of materials at the atomic level, scientists when from macro to micro, and now to the nanoscale. Its a known fact that the atomic radii of elements is of the order of a few 10s of angstroms (10 to the -10 meters). So essentially, when we talk of nano technology, we are talking about just a few atoms or molecules - the idea of stacking them together and their interaction with each other and the external environment. The implications of these are enormous. For instance, in the chip industry, as the sizes of the transistors keep shrinking, ultimately they are going to reach a stage where just a couple of atoms are going to be defining a transistor. This is what nanotechnology is all about. \n\nThe idea of "machines" is different at the nano scale. For example, a typical nano-motor wouldn't have shafts, like we're used to seeing. It might just consist of a structure made out of some piezoelectric material which undergoes nano-deformation upon application of a small electric field. Numerous such examples can be cited.\n\nAs for how it is done, one of the methods by which its implemented is through sputtering. Speaking in lay man terms, this is like building walls to the house, brick by brick, except in this case, the bricks are atoms themselves.

The biggest challenge in nanotechnology is to be able to make devices that small that can be controlled.  I don't mean in a scary science fiction manner, but lets use a nanoelectronic computer logic gate as an example.  All electronic devices require at least two electrical contacts.  In the nanometer sized realm,making these small electronic entities is a daunting task let alone being able to take these entities (that are up to 100 times smaller than normal very small electronic entities) and manipulate them, hook up wires etc...  That is why to date there are no true real nanodevices on the market (for example,  I have heard something called nano and it was 970 nanometres long, which is actually 0.97 micrometres, the dimensions of many microcomputer components.\nAnother example is in molecular electronics (a closely related field to nanotechnology).  There are no real methods to attach two ends of a molecule (that contains the proper electrical behaviour) in a controlled manner in order to make proper electrical contact.

One really easy answer is DNA sequencing. Nanotechnology deals with objects measured in the billionths of a meter. Most say objects less than 100 nanometers. Therefore, although the length of a DNA Strand is way to long to be considered Nanotechnology the individual base pairs fit into nanotechnology perfectly.

Nanotechnology has been a hot topic in the hacker subculture\never since the term was coined by K. Eric Drexler in his book\n"Engines of Creation", where he predicted that nanotechnology\ncould give rise to replicating assemblers, permitting an\nexponential growth of productivity and personal wealth.\n(there's an authorized\ntranscription at `http://www.foresight.org/EOC/index.html.').

It is the cross disciplinary study of merging nanotechnology and genetics; i.e using nanostructure to create nanometer size machine. For example, a nanosize red blood cell would be used to cure some ailments.
