Abstract

The invention relates to a method for coating surfaces with micro- and nanoparticles, the micro- and nanoparticles being chemically bonded to the surface, comprising the steps of pre-treatment of the surface with a plasma method, simultaneous or subsequent application of the micro- and nanoparticles to the surface, and subsequent fixation of the micro and nanoparticles on the surface using a plasma method, characterized in that the fixation of the micro- and nanoparticles takes place with the aid of anisothermal plasmas, the median electrical energy of which lies in the range of the bond dissociation energy of the micro- and nanoparticles, thus allowing the strength of the chemical bond between the surface and the micro- and nanoparticles to be variably set.
