  1. Nanotechnology

  2. What it is • The term “Nanotechnology” was popularized in the 1980’s by Eric Drexler • Building machines at the molecular scale • Uses “Molecular Manufacturing” & “Mechanochemistry”

  3. History • Nanotechnology first theoretically mentioned in 1959 – by Richard Feynman in his book “There’s Plenty of Room at the Bottom”. • The term was first used by: Norio Taniguchi in 1974. “The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom” ~Richard Feynman

  4. The Four Generations • Mihail (Mike) Roco of the “US National Nanotechnology Initiative” described the 4 generations of nanotechnology in 2010 • http://crnano.org/whatis.htm (More on the 4 generations) 1st gen.=single process 2nd gen.=multi process 3rd gen.=linking 2nd gen. 4th gen.=“molecular factories”

  5. Current Uses • Most funding is through the U.S. military • Creating: Battlesuits, Communication devices, Coatings, Medicines & Sensors. • http://www.azonano.com/article.aspx?ArticleID=3028(More on the military application)

  6. Application (Battlesuits/Communication Devices) • Battlesuits • Fabric can tell when it is being impacted • Chem/Bio warfare protection • “Artificial Muscles” • Communication Devices • Can be built into uniforms • Can show vital signs: pulse rate, physical condition,

  7. Application(Coatings/Medicines) • Coatings • Rust/corrosion resistant • Stealth Coatings • Medicine • Automatic drug delivery systems • Instantaneous wound healing • “Hemorrhagic shock” –battlefield treatment

  8. Application(Sensors) • Sensors – wide array of sensors • Discover airborne pathogens (bio-chem warfare) • Constant health monitoring (of every soldier) • Exact GPS positioning built into equipment

  9. Future? • Involve heavy investment into Nanotech. • It will encompass every aspect of technology • Estimated to happen around the year 2020 • Biggest constraint will be financial, not technological
