Synthesis and Characterization of Magnetic Nanoparticles for Biomedical Applications

Although magnetic nanoparticles have been synthesized since the 1960’s, most methods to obtain them yield particles with sub-optimal magnetic properties. Furthermore, many formulations intended for use in aqueous-phase result in rapid aggregation and precipitation in biological environments and in cell culture media. These limitations seriously hinder development of new biomedical applications of magnetic nanoparticles, such as nanoscale thermal therapy, magnetic particle imaging, and therapeutic delivery. Our group has made fundamental contributions to the synthesis and characterization of magnetic nanoparticles for biomedical applications by developing methods to synthesize nearly defect free particles with optimal magnetic properties, inexpensive and scalable methods to coat magnetic nanoparticles with covalently grafted layers of polysaccharides and polymers, and reporting rigorous methods of magnetic characterization with an emphasis on applications of these materials in time-varying magnetic fields.
