Nanotechnology relates to the production, research and use of extremely small nano structures. The word 'nano' comes from the Greek language and means 'midget'. One nm (short for nanometre) equals one millionth of a millimeter or in other words one ten thousandth of the thickness of one human hair. The nanometre scale is the scale of single atoms and tiny molecules. One nanometre represents about 4 to 6 atoms. Particles on a nano scale, so called nano particles, or polymers (smaller than 100nm) are the building blocks of this technology. The ability to utilise materials on the atomic level and the use of the unique phenomena that occur on that small scale, give a huge amount of possibilities for almost every field, for example energy and conservation technology, IT business, medicine and pharmaceutical industries. On an atomic level, there are no borders between chemistry, biology and physics. It all comes together into interdisciplinary technology, that means no demarcation for lots of branches.

Whether around the house, in car businesses, aircraft engineering, material engineering or computer businesses, nano particles enable surfaces to become extremely tear and scratch proof with long protection against corrosion and a high sliding ability.

When molecules that normally bustle about unorganised in materials, are structured in a way that each atom stay where it should be, the impossible becomes possible. Materials get new powers when the atoms are controlled and closely arranged. Production processes become cheaper and more environmentally friendly. Nanotechnology manipulates molecules through current, magnetism or chemistry, so that they organise themselves. Nature serves as the model for that: the cell and its function. The aim of nanotechnology is making molecules organise themselves without the help of a human. If possible, these molecules should also reproduce themselves. Japanese scientists have made this possible already.

Nanotechnology is setting a trend for the future decades and opens new markets. Experts and the media name it the key technology of the 21st century.

The research in this field is supported by research institutions and businesses in EU . There are special competence centres, which specialise in the field of nanotechnology. These competence centres are linked with, for example large firms, colleges, universities, research institutions and chambers of commerce. Venture capitalists, federal government and states finance these projects. Nanotrading® s.r.o is one of the first companies in Slovakia to deal with material nanotechnology, programming, location and usage of nanotechnology and nanoproducts in different industrial branches.
