Exploiting the non-linear dynamic magnetic behavior of magnetic nanoparticles in biomedical imaging

In this nexMPI training school presentation, Dr. Frank Wiekhorst from Physikalisch-Technische Bundesanstalt (PTB), Germany, explores the non-linear dynamic magnetic behavior of magnetic nanoparticles and its applications in Magnetic Particle Imaging (MPI). The presentation covers the fundamental principles of MPI, different imaging approaches, and methods for evaluating nanoparticle tracer performance using Magnetic Particle Spectroscopy (MPS) and AC magnetometry. Particular attention is given to the influence of nanoparticle properties and local biological environments on imaging performance, highlighting current challenges and future perspectives for biomedical MPI applications.
