CONCLUSION

What is

nanotechnology ?

Nanotechnology is …

A science whose theme is

the control of matter on an

atomic and molecular scale

How small is the Nano Scale ?

One nanometer is one billionth, or 10-9 of meter.

One humain hair is about 100,000 nanometers.

DNA filament10 nm

HISTORY…

1959 : Richard Feynman won a Nobel prize for « fundamental work in quantum electrode » ‘‘There’s plenty of room at the bottom’’

’’ il y a plein d'espace en bas ’’

1985, researchers reported the discovery of the ‘‘buckyball’’ A “Buckyball.”

0.7 nm

1991 discovery of related molecularshape know as the ‘‘ carbonnanotube ’’ A “Carbon Nanotube”

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

IN

Cancer treatment :

Nanorobotics :

• Cancer cells can be killed without the painfull sideeffect of chemotherapy.

•Diagnostic, Treatment and repair

BENEFICE

Improvement in shuttles and spaceport

• using nano particles we can expect computers of size of just a little sugar cube.. without compromising on any of its usual functions.

Space Benefice of Nanotechnologie…

Cheaper space flights

Nano foods …

• Preservation of food without refrigeration

• Protection of food from bacteria and diseases

• Lighter foods

Implication and Risks of Nanotechnology…

Potentiel risks of nanotechnologie can broadlygrouped into three areas :

• Health issues :

• Environmental issues :

• Societal issues :

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.
