Characterizing the performance of commercial magnetic particles for magnetic particle imaging

The properties of magnetic nanoparticles (MNPs) are key to the effectiveness of magnetic particle imaging (MPI). While commercial MNPs are used extensively in clinical and research applications, there are still challenges in understanding the effect of certain MNP properties on its resolution and sensitivity. Being able to understand these trends will enhance efforts in optimizing parameters in MNP production for specific applications. In this study, we looked at MNP core size, clustering, and coating and their effects on its FWHM, and compared the sensitivity of different commercial particles. We identified a trend in FWHM and MNP core size as well as effects of certain coating on FWHM
