| Zusammenfassung | Magnetorelaxometry (MRX) of magnetic nanoparticles (MNPs) with optically pumped atomic magnetometers (OPMs) demands very specific and not commonly attainable performance characteristics of the sensors. While calling for ultimate magnetometric sensitivity, magnetorelaxometry relies on the capability of the sensor to detect an MNP sample’s field evolution with minimal delay after a strong multi-millitesla excitation pulse. Magnetometers must provide both high bandwidth for detection of the fast relaxation phase and high long-term stability in tracking of its slow phase. Clinical applications of magnetorelaxometry also call for compact, biocompatible, and robust sensors and will greatly profit from time-resolved imaging of the field patterns on the organ scale. We discuss recent advances in the development of OPMs capable of addressing relaxometry prerequisites and pay special attention to the pilot implementation of the first commercially available kHz-bandwidth OPM sensor for MRX. |
