    IMPLICATION
    CONCLUSION
  • 3. Whatis
    nanotechnology ?
  • 4. Nanotechnologyis …
    A science whosethemeis the control of matter on an atomic and molecularscale
  • 5. How smallis the Nano Scale ?
    • One nanometeris one billionth, or 10-9 of meter.
    • 6. One humain hairis about 100,000nanometers.
    DNA filament
    10 nm
  • 7. HISTORY…
    • 1959 : Richard Feynman won a Nobel prize for « fundamentalwork in quantum electrode »
    ‘‘There’splenty of room at the bottom’’
    ’’ il y a plein d'espace en bas ’’
    • 1985, researchersreported the discovery of the ‘‘buckyball’’
    A “Buckyball.”
    0.7 nm
    • 1991 discovery of relatedmolecularshape know as the ‘‘ carbon nanotube ’’
    A “Carbon Nanotube”
  • 8. Impact on Everyday life…
    • today, the Nanoparticules, the most frequently used (65%) is silver, and in a least measures the carbon (17%). Come then titanium, the silica, zinc and gold.
    Silica( salt, sugar, cream)
    Titanium
    Titanium, Silver, silica and carbone
  • 9. OTHER APPLICATIONS OF NANOTECHNOLOGY
  • 10. IN
  • 11.
    • Cancer treatment:
    • 12. Cancer cellscanbekilledwithout the painfullsideeffect of chemotherapy.
    • 13. Nanorobotics:
    • 14. Diagnostic, Treatment and repair
  • BENEFICE
  • 15. SpaceBenefice of Nanotechnologie…
    • Improvement in shuttles and spaceport
    • 16. using nano particles we can expect computers of size of just a little sugar cube.. without compromising on any of its usual functions.
    • 17. Cheaperspaceflights
    • 18. Nano foods …
    • 19. Preservation of foodwithoutrefrigeration
    • 20. Protection of foodfrombacteria and diseases
    • 21. Lighterfoods
  • Implication and Risks of Nanotechnology…
    • Potentiel risks of nanotechnologie canbroadlygroupedintothree areas :
    • 22. Health issues :
    • 23. Environmental issues :
    • 24. Societal issues :
  • Conclusion
    • However, if the researchers in this field put together an ethical set of guidelines and follow them, then we should be able to develop nanotechnology safely while still reaping its promised benefits.
    Nanotechnology is predicted to be developed by 2020 but much depends on our commitment to its research.
