People » Xiaohu Xia


Dr. Xia’s research focuses on developing advanced functional nanomaterials and applying them to technologically important applications such as medical diagnostics and bio-/chemical sensing. In basic research, he carefully engineers nanostructures with precisely controlled sizes, shapes, and chemical compositions by manipulating the thermodynamic and/or kinetic parameters during nanocrystal synthesis. He is interested in understanding fundamental nanocrystal growth and the structure-property relationships. In applied research, he is committed to addressing challenge issues of current medical diagnostic techniques by taking advantage of the unique properties of nanomaterials. The ultimate goal is to develop highly sensitive, reliable, and low-cost diagnostic kits that are particularly suitable for clinical uses.
