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.

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.

Nanotechnology is the science and technology of building electronic circuits and devices from single atoms and molecules.  It deals with devices typically less than 100 nanometers in size and is expected to make a significant contribution to the fields of computer storage, semiconductors, biotechnology, manufacturing and energy.  So it's scope is extremely vast.\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.  There's even been talk of possibly using nanotechnology in warfare, unfortunately.\n\n-Colourgirlie ^_^.

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.

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."

Firstly, finding an adequate power source, and secondly, with current progress the world's smallest motor is about 30 atoms wide, which would still be far too large to make a nanobot of sorts that could operate inside the body.

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.

Dictionary.com defines a robot as:\n\n1) A mechanical device that sometimes resembles a human and is capable of performing a variety of often complex human tasks on command or by being programmed in advance.\n2) A machine or device that operates automatically or by remote control.\n\nI believe that though it is not entirelly specified in the latter of the two definitions, a robot much be mechanical - it must have movement. Computers are used with and in robots, but computers themselves are not robots.

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.

Electrobotics\n\nThe Electrobotics Company was on the verge of a major world-changing discovery when its research developer/scientist, Brian Childs, figured out a way to connect human DNA to its prototype robot, DEX-4. A robot with the ability to think and rationalize could have mind-staggering effects, on the world not to mention mind staggering profits for the company.

It is true that nanotechnology is about creating things smaller than the eye can see, they don't necessarily have to be machines in the traditional sense.\n\nNanotechnology, rather, has become a scientific buzz-word used to describe phenomena on the nanoscale, 0.000000001 meters. What is this small? Well, atoms are generally 1/10th of a nanometer... So if you put a bunch of atoms together, you've got a nanometer.\n\nSome people think of nanotechnology just as making teeny machines (with gears and all), but the field is so much broader than that. Researcher of biological proteins often call their work nanotechnology. Really anything that involves surface interactions or self-assembly is nanotechnology.\n\nAnyway, check out quantum dots. According to Wikipedia, they've made it into Playstations.

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
