Polynuclear manganese complexes are used as precursors for the synthesis of manganese oxide nanoparticles (MnO NPs). Altering the thermal decomposition conditions can shift the nanoparticle product from spherical, thermodynamically-driven NPs to unusual, kinetically-controlled octapod structures. The resulting increased surface area profoundly alters the NP's surface-dependent magnetism and may have applications in nanomedicine.

A single source bimetallic precursor is used in the synthesis of octahedral Gd:Fe3O4nanoparticles in order to reduce separate nucleation.

We report a single-step, microwave-assisted approach for the preparation of multifunctional magnetic nanocomposites. We demonstrate the link between synthetic methodology and the functionality of the nanocomposites as biomedical imaging agents.
