text: what is nano technology? could you please explain about this?   nanotechnology  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.  envisioned 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.  larry 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." see afm, stm, buckyball, nanotube and mems.
