It represents the technology for a new age: The nanotechnology leads us to a world, which cannot be registered by optical instruments, as their structures are smaller than the wavelength of visible light. The invisible world is in front of us. Welcome to the Nano cosmos.

If as a child you once analyzed once the membrane of an onion, parts of a flower or hair under a microscope, you definitely remember the curious and fascinating pictures which appeared in the middle of glimmering refraction effects in the ocular. You find the light microscope more in schools than in research laboratories. Although they are useful for some research work, many scientists are anxious to enlarge their field of vision in the area beyond the microscopic world.

A new strange world exists, which is basically not ascertainable by optical instruments, as their structures are smaller than the wavelength of visible light. As we measure sizes and distances in Nano meters (a millionth of a millimeter), we name this empire of invisibility the Nano cosmos. Roughly speaking the Nano cosmos contains objects which are bigger than atoms and smaller than a cell. It concerns the world of molecules, from the small (as glucose) up to the comparatively gigantic chain molecules of a living cell, for example proteins and nucleic acids.

If you think of a meter as the size of the world, by comparison a nanometer is the size of a marble. A man's beard will grow one nanometer in the time it takes him to lift his razor from the washroom sink to his face.

From the Greek “nanos” (dwarf)

A Nano metre (nm) =one billionth of a metre

A human hair is approximately 50,000 nm wide
