2 Points to consider What is nanotechnology all about History Advantages
Disadvantages Conclusion

3 Menu Nanotechnology? Nanotech is a study of manipulating matter on an atomic and molecular scale It deals with developing materials, devices, or other structures possessing at least one dimension sized from 1 to 100 nanometres.

4 Nanotech History It is a relatively recent development in scientific research but the development of its central concepts happened over a longer period of time. The emergence of nanotechnology was in the 1980s. Invention: scanning tunneling microscope (1981) – an instrument for imaging surfaces at the atomic level. Discovery: the fullerene (1985) – any molecule composed entirely of carbon, in the form of a hollow sphere, ellipsoid, or tube.

7 The Nanometre An atom is a million times smaller than the thickest human hair. The diameter of an atom ranges from about 0.1 to 0.5 nanometers (1 × m to 5 × m). Back to Nanotech

8 Menu Advantages auto windows that don’t produce condensation when variation of temperature the skin tissue regeneration microrobots able to destroy the bacteria and tartars in your mouth 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? 

9 Menu Disadvantages There is currently limited understanding of the risks nanotech implies Diamonds will lose its value as it now can be mass produced More accessible, powerful and destructive weapons Presently, nanotechnology is very expensive Is it really a disadvantage?

10 Menu Conclusions Nanotechnology is a welcome field in science, as it helps the humanity to find solutions to his issues. Everybody will be happy, less or more! Nanotechnology lives up to our expectation and even crossed them. This is on big step for everyone, that can either lead to humanity satisfaction or to World War III.
