Superparamagnetic iron oxide nanoparticles are used in applications such as target delivery, magnetic resonance imaging, hyperthermia and magnetic separation; however, nanoparticle synthesis often requires a sophisticated ligand exchange reaction to add the right functional groups to the nanoparticle surface. In this Hot Communication Charles J. O’Connor and co-workers at University of New Orleans and the University of Bordeaux report the synthesis of polyamine stabilized magnetite nanoparticles that are highly stable in aqueous solution. The surface amine groups are also readily available for further modification. Read for free until 12th April (free registration required)
