In this paper we have presented a new method for the synthesis of metal-oxide nanoparticles. Nanoparticles are synthesized on the surface of a metal by using low-pressure nonequilibrium and highly reactive oxygen plasma. Plasma is a rich source of oxygen atoms, which react with the surface of the sample. Because of nonequilibrium situation in plasma, localized growth of metallic oxide nanoparticles occurs on the surface of the metal. The method is extremely fast and efficient. Nanoparticles are formed already in few seconds of treatment.

We have shown an example of the use of oxygen plasma for controlled surface modification of polymer material, which is widely used in medical applications. By non-equilibrium oxygen plasma we can influence the surface morphology, wetting behaviour, adhesion properties of the surface and formation of new functional groups on the surface. This functional groups act as binding sites for further attachment of proteins like streptavidin. The procedure is therefore suitable for improving the biocompatibility of polymer surfaces to which we can link proteins or other bioactive molecules.
