Magnetic nanoparticles have emerged as important materials in health and enviromental research, capable for example of the diagnosis, imaging and selective destruction of tumors, but also on other issues such as the purification of heavy metals in water. In this framework, our research interest is aimed to the production of biocompatible core-shell structured nanoparticles where the magnetic entities may serve as multipurpose local probe, as contrast agent for magnetic resonance imaging (MRI) and/or as a heating dissipation center for hyperthermia. In addition, nanoparticles can also be capable of absorbing heavy metals, such as arsenic, that can simply remove lately with an external magnetic field. |
