Fluorescent core-shell magnetic nanoparticles by type II photoinitiated polymerisation.

Abstract

We report a fluorescent monomer-free method for the synthesis of fluorescent and stable magnetic nanocomposites using a benzophenone/rhodamine B bimolecular photoinitiator system. The method allows the synthesis of a fluorescent polymer shell layer around magnetic nanoparticles in one step by UV irradiation at ambient temperature.
