Synthesis of ferromagnetic polymer coated nanoparticles on multi-gram scale with tunable particle size

The synthesis of ferromagnetic cobalt nanoparticles with polymeric ligands with tunable particle size is reported on multi-gram scales. End-functional polystyrene ligands were prepared via atom transfer radical polymerization. Mechanistic studies on this system were conducted as well as direct comparisons of polymer vs. small molecule ligand effects on nanoparticle formation.
