what nanotechnology mean?

Engineering of functional systems at the molecular scale. This covers current work and concepts that are more advanced. In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products. Nanotechnology research has focusly primarily on molecular manufacturing -- the creation of tools, materials, and machines that will eventually enable us "to snap together the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of physics." A leading nanotech scientist describes past efforts at molecular level manufacturing as attempts to assemble LEGO pieces while wearing boxing gloves. Nanotechnology, he believes, will enable us to take off the gloves and build extraordinary things. The timeline of nanotech history usually begins with a talk given in 1959 by physicist Richard Feynman, titled "There's Plenty of Room at the Bottom." The next milestone comes in 1981, when MIT graduate student K. Eric Drexler, inspired by Feynman, published an article called "Protein design as a pathway to molecular manufacturing." This is followed by Drexler's definitive 1986 book, Engines of Creation, now available on the Web in its entirety.

I think its shrinking in size to be able to be movable enough of technology like computers: from pc to lap tops and the likes. greetings. : )

nanotechnology was created for the use of many applications including surgery to the most smallest detail where normally a surgeon would have to cut open someone, they would just have to inject the nanobots into the blood stream around the area that needs surgery. this concept is still being worked on, but medical and technological science is making progress.

Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged. If we rearrange the atoms in coal we can make diamond. If we rearrange the atoms in sand (and add a few other trace elements) we can make computer chips. If we rearrange the atoms in dirt, water and air we can make potatoes. Todays manufacturing methods are very crude at the molecular level. Casting, grinding, milling and even lithography move atoms in great thundering statistical herds. It's like trying to make things out of LEGO blocks with boxing gloves on your hands. Yes, you can push the LEGO blocks into great heaps and pile them up, but you can't really snap them together the way you'd like. ITS ALL THE MATTER OF SIZE WHICH WILL GET REDUCED BY 10^-9.

have you heard about microbiology?if yes then nanotechnology is an equivalent term is electronics.nano means 10^-9.so now you can imagine how small things it is dealing with?

In nanotechnology, basically grouping of smalll small atoms are studied. Interesting field !

its the study of small level matter

nanotechnology deals with things tat are of da size of nanometers..it is impossible to see those things using our normal microscope..ve need an electronic microscopic microscope..in nano technology ve research abt robots tat are of da nano size..

yea...Nanotechnology is a field of applied science focused on the design, synthesis, characterization and application of materials and devices on the nanoscale. Nanotechnology is a sub classification 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.

Nanotechnology is a field of applied science focused on the design, synthesis, characterization and application of materials and devices on the nanoscale. Nanotechnology is a sub classification 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.

Advanced nanotechnology, sometimes called molecular manufacturing, is a term given to the concept of engineered nanosystems (nanoscale machines) operating on the molecular scale. By the countless examples found in biology it is currently known that billions of years of evolutionary feedback can produce sophisticated, stochastically optimized biological machines, and it is hoped that developments in nanotechnology will make possible their construction by some shorter means, perhaps using biomimetic principles. However, K Eric Drexler and other researchers have proposed that advanced nanotechnology, although perhaps initially implemented by biomimetic means, ultimately could be based on mechanical engineering principles (see also mechanosynthesis) In August 2005, a task force consisting of 50+ international experts from various fields was organized by the Center for Responsible Nanotechnology to study the societal implications of molecular nanotechnology [3]. Determining a set of pathways for the development of molecular nanotechnology is now an objective of a broadly based technology roadmap project [4] led by Battelle (the manager of several U.S. National Laboratories) and the Foresight Institute. That roadmap should be completed by early 2007. There exists the potential to design and fabricate artificial structures analogous to natural cells and even organisms.
