Nanotechnology

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”

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

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”

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)

Application (Battlesuits/Communication Devices) 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,

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

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

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
