This covers current work and concepts that are This covers current work and concepts that are more advanced. more advanced. In its original sense, nanotechnology refers to In its original sense, nanotechnology refers to the projected ability to construct items the projected ability to construct items from the from the bottom upbottom up, using techniques and tools being , using techniques and tools being developed today to make complete, highly developed today to make complete, highly advanced products. advanced products.History NanotechnologyHistory NanotechnologyThe concept of nanotechnology was first The concept of nanotechnology was first proposed by the Nobel laureate proposed by the Nobel laureate Richard P. Richard P. FeynmanFeynman in in 19591959 in an after dinner speech at in an after dinner speech at the the Annual Meeting of the American Physical Annual Meeting of the American Physical SocietySociety..He said “the principles of physics, as far as I can He said “the principles of physics, as far as I can see, do not speak against the possibility of see, do not speak against the possibility of maneuvering things atom by atom. It is not an maneuvering things atom by atom. It is not an attempt to break any laws; it is something, in attempt to break any laws; it is something, in principle, that can be done; but in practice, it has principle, that can be done; but in practice, it has not been done because we are too big.”not been done because we are too big.”What is the meaning of What is the meaning of Nanotechnology?Nanotechnology?Nan·o·tech·nol·o·gy (năn' -tĕk-nŏləNan·o·tech·nol·o·gy (năn' -tĕk-nŏlə''-jē)ə-jē)ə n.n. The term “Nanotechnology” was defined by Tokyo The term “Nanotechnology” was defined by Tokyo Science University Professor Norio Taniguchi in a Science University Professor Norio Taniguchi in a 1974 paper.1974 paper.Nanotechnology is the science of developing Nanotechnology is the science of developing materials at the atomic and molecular level.materials at the atomic and molecular level.The devices are typically less then a 100 The devices are typically less then a 100 nanometers in size!nanometers in size!One nanometer equals one thousandth of a One nanometer equals one thousandth of a micrometer or one millionth of a millimeter or about or one millionth of a millimeter or about how much your fingernails grow each second. how much your fingernails grow each second.Who developed Nano technology?Who developed Nano technology?Nanotechnology was developed overtime not by Nanotechnology was developed overtime not by one company or one person’s but many hard one company or one person’s but many hard and long years of research by scientist, and long years of research by scientist, company’s, and government agency’s. company’s, and government agency’s.Benefits and Risks of Benefits and Risks of NanotechnologyNanotechnologyNanotechnology covers a wide Nanotechnology covers a wide range of industries.range of industries.Telecommunications and Telecommunications and Information Technology could Information Technology could benefit in terms of faster benefit in terms of faster computers and advanced computers and advanced storage.storage.Health care could see benefits Health care could see benefits in terms of skin care and in terms of skin care and protection, advanced protection, advanced pharmaceuticals, drug delivery pharmaceuticals, drug delivery system, biocompatible system, biocompatible materials, and nerve and materials, and nerve and tissue repair.tissue repair.The power of the technology The power of the technology may cause two competing may cause two competing nations to enter a disruptive nations to enter a disruptive and unstable arms race.and unstable arms race.Weapons and surveillance Weapons and surveillance devices could be made small, devices could be made small, cheap, powerful, and very cheap, powerful, and very numerous. numerous. Cheap manufacturing and Cheap manufacturing and duplication of designs could duplication of designs could lead to economic upheaval. lead to economic upheaval.Nanotechnology RevolutionNanotechnology RevolutionEric Drexler Eric Drexler who is most who is most accredited with pushing accredited with pushing the nanotechnology the nanotechnology revolution to where it is revolution to where it is today by raising public today by raising public awareness, educating awareness, educating future researchers, and future researchers, and generally expounding generally expounding upon the field. He was upon the field. He was awarded the first PhD in awarded the first PhD in nanotechnology ever.nanotechnology ever.Do we use Nanotechnology?Do we use Nanotechnology?Nanocomposite materials are currently being used on General Motors Nanocomposite materials are currently being used on General Motors and Toyota production cars. The new materials are more scratch and Toyota production cars. The new materials are more scratch resistant and lighter. The impact of such nanocomposite materials is resistant and lighter. The impact of such nanocomposite materials is set to be huge as lower weight results in lower fuel consumption and set to be huge as lower weight results in lower fuel consumption and minor accident damage could be eliminated. minor accident damage could be eliminated. AngstroMedicaAngstroMedica has produced a nanoparticulate-based synthetic bone has produced a nanoparticulate-based synthetic bone by manipulating calcium and phosphate at the
