  1. Nanotechnology Group 2 Jason Hill Ryan Long Joye Turnage Jonathan Ashworth

  2. Overview • What is Nanotechnology? • Brief History/Development • How Nanotechnology impacts us today • Future applications • Conclusion

  3. What is Nanotechnology? Described as: • The direct control of atoms and molecules for materials and devices • Consists of the processing of separation, consolidation, and deformation of materials by one atom or molecule

  4. History/Development Nanometer: 1 billionth of a meter 1 millionth of a millimeter Moore’s Law: the complexity of an integrated circuit, with respect to minimum component cost, will double every 18 months

  5. History/Development 1974: The term Nanotechnology first coined by Professor Norio Taniguchi 1980’s: Concepts of Nanotechnology were explored in much more depth by Dr. Eric Drexler

  6. 3 Steps for Implementation • Manipulating atoms individually • IBM spelled on surface of a nickel crystal using atomic force microscope • Develop assemblers • Moves atoms and molecules to their correct locations • Develop replicators • Used to build more assemblers

  7. Nanocomposites Used to make existing products stronger and more lightweight • Bumpers, “step assists”, metal rubber, etc. Impacts: • Lower vehicle weight & increased gas mileage • Fewer auto repair claims

  8. Nanocrystals • Up to 300% harder than the same bulk material • Size determines color Examples: Wound dressing that kills bacteria in 30 minutes

  9. Nanoparticles Examples: • Stain resistant pants (Eddie Bauer) • Sunscreen (UV light defender) Impacts: • Reduced dry cleaning, more economical sunscreen

  10. Nanoclays and Nanocomposites Allows for lighter weight and greater shelf-life for product packaging Impacts: • Reduced transportation costs • Beer will gain 60 additional days of shelf life

  11. Nanotechnology Today Current Uses of Nanotechnology • Computer Processors • Ipod Nano • Air purifier • Socks • Many more

  12. Future Applications • Boost cell phone or laptop battery life • Cut gas consumption • Improve methods for oil drilling • Convert human movement into harnessed energy • Endless others

  13. Future Applications Motorized nanocars powered by light • Current car is only about the size of one DNA molecule (3x4 nanometers)

  14. Future Applications Fighting prostate cancer • Carries cancer drug docetaxel • Studded with aptamers to link to cancer cells • Equipped with polyethylene glycol to resist defenses of the tumor cell

  15. Conclusion Nanotechnology will substantially change the manufacturing process of almost every product in existence. Whatever happens it is likely to be the human race’s greatest scientific achievement to date and will probably change all of our lives.
