摘要

Remote sensing of magnetic nanoparticles (MNPs) has exciting applications for MNP hyperthermia and molecular detection. We introduce, simulate, and experimentally demonstrate an innovation-a sensing coil that is geometrically decoupled from the excitation field-for MNP spectroscopy that increases the flexibility and capabilities of remote detection. The decoupling enhances the sensitivity absolutely; to small amounts of nanoparticles, and relatively; to small changes in the nanoparticle dynamics. We adapt a previous spectroscopic method that measures the relaxation time of nanoparticles and demonstrate a new measurement of nanoparticle temperature that could potentially be used concurrently during hyperthermia.
