Superparamagnetic iron oxide nanoparticles (SPIONs) are inorganic nanomaterials gaining strong clinical interest due to their increasing number of biological and medical applications. The stabilization of SPIONs in a biocompatible stable suspension (bioferrofluid) is generally achieved by an adequate polymeric coating.
