A method for the postdeposition org. coating of metallic nanoparticles is introduced. FePt nanoparticles from the gas phase are deposited onto Si substrates which are pre-coated with multilayers of phospholipid mols. by spin coating. If the substrate temp. is just below or above the temp., at which the phospholipids undergo a phase transition from the liq. cryst. into an intermediate phase, the particles are enwrapped by the lipids. The particles exhibit a clear tendency to self-assemble in regular two-dimensional particle arrangements.
