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.

Check out nanotechnology, the science and technology of building electronic circuits, devices, etc., from single atoms and molecules. \n\nThe science of construction in which dimensions of the components are less than 100 nanometers (nm; 10−9 of a metre), this is 100,000 times thinner than a human hair.\n\n The term was introduced by Nomo Taniguchi in 1974 to refer to mechanical machining methods. \n\nTop-down nanotechnology concentrates on manufacturing on this very small scale. Techniques such as photo lithography are used to make transistors for integrated circuits; the smaller the transistor, and the closer together they are packed, the higher the processing power of the chip. An Intel Pentium chip has about 1·5 million transistors. A specialized Dynamic Random Access (DRAM) chip carries 64 million transistors. \n\nBottom-up nanotechnology builds with individual atoms. \n\n\nThis area of new technology may hold the most promise on the horizon.

Nano technology is science fiction at this point.  You may want to try watching The X-Files or old Star Trek episodes... or ask the Borg.

Have you read "Prey" by Michael Creighton? I read this several years back before the world had heard of nanotechnology. It was enough for me to decide that it scares the beejeezus out of me. Granted.......it was a book. But the thought that these atoms could almost take on a life of their own is a bit disconcerting.

if you mean nanotechnology then:\nNanotechnology comprises technological developments on the nanometer scale, usually 0.1 to 100 nm. (One nanometer equals one thousandth of a micrometre or one millionth of a millimetre.) The term has sometimes been applied to microscopic technology.\nNanotechnology 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. 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." Such phenomena include quantum confinement--which can result in different electromagnetic and optical properties of a material between nanoparticles and the bulk material; the Gibbs-Thomson effect--which is the lowering of the melting point of a material when it is nanometers in size; and such structures including carbon nanotubes. Nanoscience and nanotechnology are an extension of the field of materials science, and materials science departments at universities around the world in conjunction with physics, mechanical engineering, bioengineering, and chemical engineering departments are leading the breakthroughs in nanotechnology. The related term nanotechnology is used to describe the interdisciplinary fields of science devoted to the study of nanoscale phenomena employed in nanotechnology. This is the world of atoms, molecules, macromolecules, quantum dots, and macromolecular assemblies, and is dominated by surface effects such as Van der Waals force attraction, hydrogen bonding, electronic charge, ionic bonding, covalent bonding, hydrophobicity, hydrophilicity, and quantum mechanical tunneling, to the virtual exclusion of macro-scale effects such as turbulence and inertia. For example, the vastly increased ratio of surface area to volume opens new possibilities in surface-based science, such as catalysis.

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.

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.

For example, the vastly increased ratio of surface area to volume opens new possibilities in surface-based science, such as catalysis.\n\n\nHistory of Use\nThe first mention of some of the distinguishing concepts in nanotechnology (but predating use of that name) was in "There's Plenty of Room at the Bottom", a talk given by physicist Richard Feynman at an American Physical Society meeting at Caltech on December 29, 1959. Feynman described a process by which the ability to manipulate individual atoms and molecules might be developed, using one set of precise tools to build and operate another proportionally smaller set, so on down to the needed scale. In the course of this, he noted, scaling issues would arise from the changing magnitude of various physical phenomena: gravity would become less important, surface tension and Van der Waals attraction would become more important, etc. This basic idea appears feasible, and exponential assembly enhances it with parallelism to produce a useful quantity of end products.\n\nThe term "nanotechnology" was defined by Tokyo Science University professor Norio Taniguchi in a 1974 paper (N. Taniguchi, "On the Basic Concept of 'Nano-Technology'," Proc. Intl. Conf. Prod. Eng. Tokyo, Part II, Japan Society of Precision Engineering, 1974.) as follows: "'Nano-technology' mainly consists of the processing of, separation, consolidation, and deformation of materials by one atom or one molecule." In the 1980s the basic idea of this definition was explored in much more depth by Dr. Eric Drexler, who promoted the technological significance of nano-scale phenomena and devices through speeches and the books Engines of Creation: The Coming Era of Nanotechnology and Nanosystems: Molecular Machinery, Manufacturing, and Computation, (ISBN 0-471-57518-6), and so the term acquired its current sense.\n\nMore broadly, nanotechnology includes the many techniques used to create structures at a size scale below 100 nm, including those used for fabrication of nanowires, those used in semiconductor fabrication such as deep ultraviolet lithography, electron beam lithography, focused ion beam machining,Nanoimprint Lithography atomic layer deposition, and molecular vapor deposition, and further including molecular self-assembly techniques such as those employing di-bloc

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.

device structures used to build transistors or circuit elements that are smaller than 100 nanometers (nm) in size.\n\nA good size comparison is a virus, the smallest of microorganisms. But some layers of material that make up a transistor are even thinner than viruses; so an atom comes in handy as a measuring stick. For example, the transistor gate oxide, an insulating material, consists of about five atomic layers that add up to little more than one nanometer in thickness.\n\nSo what does all this have to do with the future of silicon?\n\nIn the past, industry experience seemed to indicate there is a very definite limit to the number components that can be fabricated onto a semiconductor wafer. Maybe that's true, with traditional methods. But as we get deeper into the realm of nanotechnology, materials and process recipes are changing. As these factors change, so do the limitations that the industry used to consider absolute. The world of nanotechnology recognizes that silicon as a semiconductor material is still extremely effective.\n\n\nAs research into nanotechnology continues to provide useful new materials or devices, it will be much more practical to commercialize these innovations by integrating them into silicon-based technology that has a massive existing infrastructure, rather than by trying to create an entirely new infrastructure.\n\nNanotechnology is slowly creeping into popular culture, but not in a way that most scientists will like. There is a great example in Dorian - novelist Will Self's modern reworking of Oscar Wilde's The Picture of Dorian Gray. In one scene, set in a dingy industrial building on the outskirts of Los Angeles, we find Dorian Gray and his friends looking across rows of Dewar flasks, in which the heads and bodies of the dead are kept frozen, waiting for the day when medical science has advanced far enough to cure their ailments. Although one of Dorian's friends doubts that technology will ever be able to repair the damage caused when the body parts are thawed out, another friend - Fergus the Ferret - is more optimistic. \n\n- Nanotechnology, Fergus - you're quite right; they'll have tiny hyperintelligent robots working in concert to repair our damaged bodies. \n\nThis view that nanotechnology will lead to tiny robotic submarines navigating our bloodstream is ubiquitous. Yet today's products of nanotechnology are much more mundane - stain-resistant trousers, better sun creams and tennis rackets reinforced with carbon nanotubes. There is an almost surreal gap between what the technology is believed to promise and what it actually delivers.
