Points to consider

0 What is nanotechnology all about0History0Advantages 0 Disadvantages0 Conclusion

Nanotechnology?0Nanotech is a study of manipulating matter on an

atomic and molecular scale0 It deals with developing materials, devices, or other

structures possessing at least one dimension sized from 1 to 100 nanometres.

Nanotech History

0 It is a relatively recent development in scientific research but the development of its central concepts happened over a longer period of time.

0The emergence of nanotechnology was in the 1980s.0 Invention: scanning tunneling microscope (1981) – an

instrument for imaging surfaces at the atomic level.

0Discovery: the fullerene (1985) – any molecule composed entirely of carbon, in the form of a hollow sphere, ellipsoid, or tube.

The Nanometre0 An atom is a million

times smaller than the thickest human hair.

0The diameter of an atom ranges from about 0.1 to 0.5 nanometers (1 × 10-10 m to 5 × 10-10 m).

Advantages

0 auto windows that don’t produce condensation when variation of temperature

0 the skin tissue regeneration0 microrobots able to destroy the bacteria and tartars

in your mouth 0 in some cases, there won’t be any need for surgery, as

nanoparticles will be able to detect tumors, injured blood vessels

No need for toothpaste?

Menu

Disadvantages

0There is currently limited understanding of the risks nanotech implies

0 Diamonds will lose its value as it now can be mass produced

0More accessible, powerful and destructive weapons0Presently, nanotechnology is very expensive

Is it really a disadvantage?

Menu

ConclusionsMenu

0 Nanotechnology is a welcome field in science, as it helps the humanity to find solutions to his issues.

0Everybody will be happy, less or more!0Nanotechnology lives up to our

expectation and even crossed them.0This is on big step for everyone, that

can either lead to humanity satisfaction or to World War III.
