Engineering Magnetic Nanoparticles for Spectroscopic Sensing and Imaging Applications

Recent years have witnessed rapid advances in diagnostic technologies spanning magnetic, optical, mechanical, and electrochemical modalities.
Despite this progress, a critical gap remains: the need for diagnostic platforms that are accessible, accurate, and cost-effective for routine clinical and translational use. In this talk, I will focus on emerging magnetic technologies that leverage magnetic nanoparticles and their unique physical properties to address pressing biomedical challenges. I will first highlight ongoing research in my laboratory on the synthesis, doping, surface functionalization, and physicochemical characterization of magnetic nanoparticles, with applications in magnetic resonance imaging (MRI) and magnetic hyperthermia therapy. I will then revisit the magnetic particle spectroscopy (MPS) technology I developed at the University of Minnesota, emphasizing its use in sensitive and quantitative in-vitro biosensing. Finally, I will describe our current efforts to develop a benchtop magnetic particle imaging (MPI) platform, aimed at enabling quantitative imaging and image-guided precision oncology.
