Contents of the Talk
In this talk, I will discuss our group’s research effort to explore the usage nano- and micro- magnetic materials and systems and spintronic devices for a variety of biomedical applications during the past two decades. First, I will briefly introduce and summarize our effort on the usage of giant magnetoresistance (GMR) devices for disease early detection. Then I will talk about the development of magnetic nanoparticle spectroscopy (MPS) technique for the detection of viruses and recent progress. Finally, I will share with you about our recent results on the usage of microcoils for neurostimulation and modulation, which can potentially address some of limits for traditional electrode-based neurostimulation.
