Have you ever cleaned your glasses with steel wool? If you can find scratches on it, than the nanotechnology is not yet brought into operation. Miniature-worlds, which are only visible with ultra modern appliances, control meanwhile our life. You can find everywhere computer chips, but infinitesimally molecules contain more possibilities:

Miniscule circuitries, frictionless surfaces, which can not be contaminated and more of such things. Follow nano to the hidden worlds:

At the limit of visibility you can find the door to the smallest world: the empire of atoms and molecules. It is only possible to have a look into this world by the use of a scanning tunneling microscope - a fine peak of charged clouds scans a surface atom-by-atom. At the same time this peak is able to monitor, but also able to take action and to move atoms.

Materials which are coated with a ultra-thin np-coating, possess special features:

For the fabrication of scratch proofed glasses nano layers are applied on the surfaces.

The result: Such glasses can be cleaned with steel wool without getting a scratch. Nano layers are so thin, that the can not deflect or break the course of light but let pass the light unchecked.
