6Concept Molecular Manufacturing
- Desktop nanofactories will use molecular raw
materials to build complete atomically precise
products

7Toxicity of Ultra-Fine Particles
- Surface area to volume ratio
- Smaller particles are more reactive
- Platinum
- Smaller molecules are more toxic
- Carbon Black

8Health 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

9Health Risks
10Environmental Issues
- Nanoparticles
- Released into the ecosystem during production and
as byproduct - Nanoproducts
- Eventually thrown away or recycled
11Environmental 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 hadnt run
dry long before.
- Uncontrollable Nanoreplicators
- Grey goo scenario isnt an imminent danger
- Distant technology
- More desirable methods
- Eventually intentional use possible

12Societal Implications
- Time to check that nanofactory!!!
13Societal Implications
- Weapons
- Improvements Innovations
- Surveillance
- Intelligence Privacy
- Economic Shifts
- Traditional exports replaced

14Societal Implications
- Corporate Control
- Patenting of Matter
- Monopolies
- Nano-hype
- Pressure to forgo RD
- Now All nano sells
- After one accident Nano is evil

15Options
- 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
16Efforts
- NNI National Nanotechnology Initiative
- CRN Center for Responsible Nanotechnology
- FDA Nanotechnology Task Force
- Nanotechnology Now
- Foresight Nanotech Institute
17Conclusion
- 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.
