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

8. Health Risks Nanoparticles Fixed Fixed Free Free ---- 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

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

11. Environmental Issues G r e y G o o "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." Drexler, Engines of Creation (1986). In Chapter 4, Engines Of Abundance http://www.crnano.org/BD-Goo.htm Uncontrollable Nanoreplicators Grey goo scenario isn’t an imminent danger Distant technology More desirable methods Eventually, intentional use possible

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

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

14. Societal Implications Corporate Control “Patenting of Matter” “Patenting of Matter” Monopolies MonopoliesNano-hype Pressure to forgo R&D Pressure to forgo R&D Now : All nano sells Now : All nano sells After one accident : Nano is evil 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
