Magnetic entities and magnetic particle spectroscopy (MPS)

Iron oxide-based nanoparticles can be engineered to be magnetically steerable, inductively heatable or chemically reactive. Joined to entites such as supraparticles, collective magnetic interaction occurs. Besides designing these magnetic interactions, we also study them via the method of magnetic particle spectroscopy (MPS) that we pioneer and consider as a very powerful tool that provides new eyes to study processes or materials when it is dark, i.e., when one cannot use (light) optical means.
