Magnetic measurement techniques assisting biomedical applications of magnetic nanoparticles — •Lutz Trahms — Physikalisch-Technische Bundesanstalt, Abbestr. 2-12, D-10587 Berlin, Germany

Due to their biocompatibiliy and their small size, magnetic nanoparticles (MNP) made of iron oxide can be guided to virtually every biological environment. MNP are susceptible to external magnetic fields and can be used, e.g., for drug transportation, heat generation or as contrast agents for MRI. All these applications require knowledge about the magnetic properties and, when applied in-vivo, quantitative knowledge about the spatial distribution in the living tissue. In this contribution, I will report on a number of magnetic measurement techniques that provide such information, i.e. in particular on conventional susceptibility measurements M(H), magnetorelaxometry, and magnetic particle spectroscopy. In addition, I will give examples how these analytical or spectroscopic techniques can be modified to obtain quantitative spatial information.
