1 Nanotechnology, Is it safe? Presented By Trevor Bethke

2 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”

3 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)

6 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 it’s the best way to treat America’s 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


8 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. Projects in Development

9 Micro-Electro-Mechanical Systems (MEMS)

10 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.
