  1. Nano-Risks Ben Philbert Cannon

  2. Why the concern? • Initial contact • Interesting aspects • Future plans http://www.imdb.com/title/tt0145487/

  3. Seminar Outline • Miracles • Health Risks • Environmental Concerns • Social Impact • Possibilities • Conclusion

  4. Look what we can do!Products http://www.forbes.com/newsletter/2006/01/10/apple-nano-in_jw_0109soapbox.inl.html http://www.voyle.net/Nano%20Products%202005/Main%20Products%202005%20.htm

  5. Look what we can do!Medical Advancements http://www.foresight.org/Nanomedicine/Gallery/index.html http://www7.nationalgeographic.com/ngm/0606/feature4/gallery5.html

  6. Concept: Molecular Manufacturing Desktop nanofactories will use molecular raw materials to build complete, atomically precise products http://www.lizardfire.com/html_nano/nano.html

  7. Toxicity of Ultra-Fine Particles • Surface area to volume ratio • Smaller particles are more reactive • Platinum • Smaller molecules are more toxic • Carbon Black Nanotechnology Risks, Ethics, and Law, Hunt, Mehta ed. 2006

  8. Nanoparticles Fixed Free Health Risks ---- Stable – Not much worry ---- Mobile – object of concern • Blood-brain barrier • Overloaded phagocytes • Arterial disease • Free radicals → cellular damage → apoptosis & genotoxicity • Protein folding errors http://en.wikipedia.org/wiki/Nanotechnology#Risks_from_nanoparticles Nanotechnology Risks, Ethics, and Law, Hunt, Mehta ed. 2006

  9. Health Risks

  10. Environmental Issues • Nanoparticles • Released into the ecosystem during production and as byproduct • Nanoproducts • Eventually thrown away or recycled

  11. Environmental Issues "Thus the first replicator assembles a copy in one thousand seconds, the two replicators then build two more in the next thousand seconds, the four build another four, and the eight build another eight. At the end of ten hours, there are not thirty-six new replicators, but over 68 billion. In less than a day, they would weigh a ton; in less than two days, they would outweigh the Earth; in another four hours, they would exceed the mass of the Sun and all the planets combined - if the bottle of chemicals hadn't run dry long before." G r e y G o o • Uncontrollable Nanoreplicators • Grey goo scenario isn’t an imminent danger • Distant technology • More desirable methods • Eventually, intentional use possible Drexler, Engines of Creation (1986). In Chapter 4, Engines Of Abundance http://www.crnano.org/BD-Goo.htm

  12. Societal Implications Time to check that nanofactory!!!

  13. Societal Implications • Weapons • Improvements & Innovations • Surveillance • Intelligence & Privacy • Economic Shifts • Traditional exports replaced http://en.wikipedia.org/wiki/Nanotechnology#Societal_risks

  14. Societal Implications • Corporate Control • “Patenting of Matter” • Monopolies • Nano-hype • Pressure to forgo R&D • Now : All nano sells • After one accident : Nano is evil http://www.ieee-virtual-museum.org/collection/event.php?id=3457012&lid=1 http://en.wikipedia.org/wiki/Nanotechnology#Societal_risks

  15. Options • Ban nanotechnology development • Stunt human advancement • Live without possible solutions to global problems • Impose no regulations on manufacturing • Possible catastrophic accidents • Unimpeded races for superior technologies • Responsible balance of caution and risk • Progress towards a better future

  16. Efforts • NNI – National Nanotechnology Initiative • CRN – Center for Responsible Nanotechnology • FDA Nanotechnology Task Force • Nanotechnology Now • Foresight Nanotech Institute

  17. Conclusion These are the years when the world changes into the world it is going to be for future generations. We must be sure it changes into something we want it to be. http://www.imdb.com/title/tt0145487/
