| The preparation of organic/inorganic hybrid magnetic colloids has been investigated as a route to synthesize novel multifunctional nanoparticles. To further modify the properties of magnetic colloids, various functional groups have been incorporated onto the polymer shell via controlled radical polymerization (CRP) techniques. Specifically, we have investigated the introduction of fluorophores to polymeric surfactants and ferromagnetic nanoparticle shells. Well defined polymer surfactants containing naphthalene and pyrene were prepared via the controlled radical polymerization methods and then used to functionalize ferromagnetic cobalt nanoparticles. Using this modular approach, the preparation of ferromagnetic colloids exhibiting fluorescent properties while dispersed in organic media was achieved. These materials are characterized by the TEM, AFM, XRD, GPC and fluorescence spectroscopy. |
