Monodisperse Conanoparticles were synthesized by thermal decomposition in the presence of aluminium alkyls yielding air-stable Conanoparticles after surface passivation. Several procedures for surfacemodification of these pre-stabilized, metallicConanoparticles are presented, including direct anchoring of surface-active functional groups and biocompatible dextran layers as well as silica and polymer coatings. As a result, individually coated nanoparticles as well as microspheres can be obtained.
