what is meant by nanotechnology?
450058
A nanometer is one billionth of a meter.  Nanotechnology is any technology which exploits phenomena and structures that can only occur at the nanometer scale, which is the scale of several atoms and small molecules.  There are proposed uses for this in many industries.  For example, nanobots could go into your bloodstream and promote healing like in sci-fi movies.

Necessary technical break-through occurs gradually. A decade back, nano-technology was beyond imagination but today it is realistic. Same way, few years from now we end up with new technology which we havent heard now. \nTechnology is like ladder, you have to make one step at-a-time to reach next step.

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.

Nano means "dwarf" in Greek and deals with technology (nanotech) on the truly small acale, like one billionth.\n\nNanotechnology tries to find new uses for material that is often highly pure and put together at the electron-microscopic scale.\n\nFor examply carbon Buckyballs are molecules that consist of 60 carbon atoms arranged by vapor deposition into what looks like tiny soccer balls.  It may be possible for these to hold and release medications, etc.\n\nSome say that when putting atoms together using nanotech, it is like adding new elements to the periodic table, thus predicting how they will react with other materials.\n\nMother Nature has always used her own nanotech to put together amazing substances (consider the diamond formed perhaps sixty miles down in a volcanic lab!).  Now we hope to do amazing things too in our much "coooler" labs.  Albany, NY is fast becoming a new center for the study and application of nanotechnology.  One company (Daystar) plans to start manufacturing cheaper film photovoltaic cells that could provide all the power we need if we shingled all our buildings with them.

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 a conceptualization of micro-biological machinery designed to work within the human body.\n\nAs of yet, it's only theory.....give it time, and it wouldn't surprise me.\n\nI saw tests on holograms in Japan just 2 years ago....so if they're managed THAT....nanotech shouldn't be too long yet.

Technology is a way of doing something.  It could be a process, a procedure or method that may or may not involve tools (technics).  When we say our technology is developing or improving, it could mean several things:\nOur methods are becoming more efficient or effective\nOur tools are getting better\nWe are teaching our technology better.

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.

Technology: The group of methods ("techniques") we use to transform the world we live in and the things in it.\n\nTechnology is a word with origins in the Greek word technologia (τεχνολογια), techne (τεχνη) "craft" + logia (λογια) "saying". It is an encompassing term dealing with the use and knowledge of humanity's tools and crafts.\n\n\nNOUN: \npl. tech·nol·o·gies \n\nThe application of science, especially to industrial or commercial objectives. \nThe scientific method and material used to achieve a commercial or industrial objective. \nElectronic or digital products and systems considered as a group: a store specializing in office technology. \nAnthropology The body of knowledge available to a society that is of use in fashioning implements, practicing manual arts and skills, and extracting or collecting materials.\n\nWant my personal one?  Technology is the reflect of humankind´s need to control rather than understand the universe.

an existence where everything becomes smaller, and we can accomodate a lot more in the same place that can't hold much now..and of course wireless technology. And a lot of involvement of non-humans in industrial processings..\n  that is, as the other guy has said, more and more towards nanotechnology.

Nanotechnology sure does have an interesting plethora of uses ranging from its use in manufacture of smaller and faster transistors for use in computers, to use as inudstrial catalysts and to use as drug targetting agents in medicine.\nHowever as you say, there is also the danger of the unknown, of proper disposal methods as well as conservation of resources.As of now though, most countries are doing a great deal of research into the field.

It is the developing of technologies on the molecular scale in the field of biology. That's really the only way to describe it, I think. Why not look it up on wikipedia?

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.

Guess you might have tried to google it but you got the spelling wrong.\n\nNanotechnology is a field of applied science focused on the design, synthesis, characterization and application of materials and devices on the nanoscale. Nanotechnology is a subclassification of technology in colloidal science, biology, physics, chemistry and other scientific fields and involves the study of phenomena and manipulation of material at the nanoscale, in essence an extension of existing sciences into the nanoscale. Two main approaches are used in nanotechnology: one is a "bottom-up" approach where materials and devices are built up atom by atom, the other a "top-down" approach where they are synthesized or constructed by removing existing material from larger entities. A unique aspect of nanotechnology is the vastly increased ratio of surface area to volume present in many nanoscale materials, which opens new possibilities in surface-based science, such as catalysis. This catalytic activity also opens potential risks in their interaction with biomaterials.

Technology that is very, very, very small. Working things that are so small you can't see them with your plain eye.
