What Is Nanotechnology?

Generally speaking, nanotechnology describes any activities at the magnitude of less than 100 nm (single drop of water spread over an area of 1 square meter would be 1/100.000.000 m thick). At this the properties of solid materials change drastically. In nanotechnology manipulation under control of the nanoscale structure and their integration into larger material occurs.

Nanoparticles are invisible duo to the fact that they are smaller than the wavelength of visible light and therefore unable to scatter light.

The material out of with the nanoparticles are made is nothing out of the ordinary. The basic material of nanoparticles can be organic or inorganic. The key characteristic is not the material itself, but the size of the particles. Nanoparticles also can be found in natural materials (for example in clay or pearl or butterfly wings) and are responsible for special properties in these materials. However, for synthesizing these materials, a so-called bottom-up chemical techniques used, i.e., one developed from the smallest size to largest sizes.

Nanotechnology will:

• Optimize existing products, by reducing weight and volume of consuming materials;
• Reduce damages and needs for maintenance;
• Customized materials and products;
• Reduce costs by emancipating the surface from underlying layers;
