Welcome to the Nanomagnetic Biosensors & Devices Group!
Led by Prof. Kai Wu, the Wu Lab is dedicated to advancing healthcare technologies through innovations in magnetic nanomaterials, spintronic devices, and intelligent sensing systems. Our interdisciplinary research integrates circuit design, physics, materials science, biology, and artificial intelligence to develop next-generation platforms for disease diagnosis and treatment. A key focus of our lab is developing spintronic devices for in-sensor computing, where sensing and computation are integrated directly in hardware to enable edge AI for healthcare applications, including neural sensing and wearable biomedical systems.
Our current research focuses on:
- Magnetic nanomaterials and spintronic nanodevices for biomedical applications;
- Wearable biosensors, including magnetic and optical sensing platforms;
- Magnetic particle imaging (MPI) and magnetic resonance imaging (MRI);
- In-sensor computing and edge AI for healthcare.
We aim to translate fundamental discoveries into practical medical technologies and welcome students and collaborators interested in interdisciplinary research at the intersection of nanotechnology, AI, and medicine.
