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

History/Development

• Nanometer 1 billionth of a meter
• 1 millionth of a millimeter
• Moores Law the complexity of an integrated
  circuit, with respect to minimum component cost,
  will double every 18 months

6
History/Development

• 1974 The term Nanotechnology first coined by
  Professor Norio Taniguchi
• 1980s Concepts of Nanotechnology were explored
  in much more depth by Dr. Eric Drexler

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

8
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

9
Nanocrystals

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

10
Nanoparticles

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

11
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

12
Nanotechnology Today

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

13
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

14
Future Applications

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

15
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

16
Conclusion

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