Title: Nanotechnology, Is it safe?

Nanotechnology,Is it safe?
Presented By Trevor Bethke

Definition of Nanotechnology
  • Nanotechnology is defined by the United States
    Environmental Protection Agency as, The
    production and use of materials at 100 nanometers
    or less. One hundred nanometers is approximately
    1/800th the width of a human hair and 1/70th the
    diameter of a red blood cell

Public Awareness
  • Public awareness is a major part to advancing
    nanotechnology. Awareness of this technology
    helps reduce risks and fear of a growing industry
    for marketing and expansion. By studying and
    assessing the risks of such a new budding
    technology reaction to any problems or setbacks
    will not destroy the research or cause perceived
    risks at a later date.

4
Opposing Views
  • Protecting the environment is the most important
    factor and biggest opponent when considering
    nanotechnology. The biggest critics against the
    wide scale use of this technology stems from the
    USEPA to ensure once nanotechnology is released
    it will be safe not only to the environment but
    the people who will be exposed to it on a
    continual basis.

5
Future of Nanotechnology
  • Self-assembling products, systems and materials
    (self repairing system)
  • Computers billions of times faster (reaching the
    size barrier of microprocessors)
  • Extremely novel inventions (self-adapting
    fabrics)
  • Realistic space travel and exploration (more
    economic)
  • NanoMedical (unique treatment delivery
    capabilities)
  • Molecular food syntheses (end of famine and
    starvation)

Big Medical Breakthroughs
  • Better Than Blood?A man-made, pure-white
    compound called Oxycyte carries oxygen 50 times
    as effectively as our own blood. Researchers are
    betting that its the best way to treat Americas
    leading cause of accidental death traumatic
    brain injury
  • Oxycyte is the newest product in a family of
    compounds known as artificial blood. The search
    for a synthetic substitute for human blood began
    at least as early as the 19th century, when
    doctors actually tried using milk to replenish
    blood loss.

Applying this to military use overseas greatly
reduces casualty rates by 40. Biggest death
related issue in Iraq is traumatic brain injury

Projects in Development
  • Entirely new kinds of material are now being
    developed. For example, NanoSonic in Blacksburg,
    Virginia, has created metallic rubber, which
    flexes and stretches like rubber but conducts
    electricity like a solid metal.
  • General Electric's research centre in Schenectady
    in New York state is trying to make flexible
    ceramics. If it succeeds, the material could be
    used for jet-engine parts, allowing them to run
    at higher, more efficient temperatures.
  • And several companies are working on materials
    that could one day be made into solar cells in
    the form of paint.

  • Micro-Electro-Mechanical Systems (MEMS)

Conclusion
  • While NanoTechnology is based in the research
    labs today, the advances made to date have
    illustrated the significant value this technology
    will bring.The implication on manufacturing
    techniques, materials manufacturing and the
    semiconductor industry will be profound. .With
    each passing day, the promise of NanoTechnology
    becomes increasingly apparent. There is a long
    way to go before the NanoMaterials production
    techniques can provide adequate supply of high
    quality materials at affordable prices. This is
    one technology that requires close monitoring to
    properly time the significant opportunities that
    will be created in it wake.
