Nanotechnology expands the possibilities for a variety of different surfaces and their properties in a revolutionary way. It replaces many aspects of microtechnology which was so popular in the 1980s.

Nanotechnology is considered by many as a key technology of the 21st Century and of the highest strategic importance. The resulting products are used, in addition to a host of new technical possibilities, for the protection of limited resources such as energy and water. In the field of surface modification, one repeatedly speaks of value, value creation and sustainability.

The prefix "nano" is derived from the Greek word "nanos" (dwarf, dwarf-like) and the ancient Greek word "nannos" (the dwarf) and relates to the size, which is usually between 1 and 100 nanometers.

A nanometer is 10-9 = 0.000 000 001 meters.
