Abstract

Poly (vinyl alcohol)–mediated synthesis of monodisperse, self-assembled, superparamagnetic maghemite particles was carried out through a magnetic field–induced biomimetic route. Modifying the kinetics of precipitation, the magnetic field promoted the nucleation of the maghemite phase over magnetite and also induced a self-assembly–assisted shape anisotropy during the precipitation of the particles in the polymer matrix.
