consisting of small particles - nanoparticles, measured in nanometers (one billionth of a meter or 80,000
times the thicken than a human hair). When the relationship size is compared, the nano-particle can be
compared with a football, and football compared with the Earth.

.
Nanotechnology is the essence is of small particles - atoms and molecules and their compounds - practical use.
Nanoparticles diameter is 80,000 times smaller than a human's hair. Researchers working with this technology
have already achieved a number of unique and sensational breakthroughs in medicine, mechanics and chemistry.
Everyone understands that protection against dirt is a variety of items (their surface) resistance to liquids and other
substances. In nature, this phenomenon is known as the lotus effect, because the lotus flower has a natural self-cleaning
mechanism, therefore, the water drops almost have no contact with the surface, as they slide down taking the dirt and
dust with them.
