toxicity of ultra fine particles
Toxicity of Ultra-Fine Particles
  • Surface area to volume ratio
    • Smaller particles are more reactive
      • Platinum
    • Smaller molecules are more toxic
      • Carbon Black

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

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

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

societal implications
Societal Implications

Time to check that nanofactory!!!

societal implications13
Societal Implications
  • Weapons
    • Improvements & Innovations

societal implications14
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

conclusion
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.
