Area(s) of Research
Dr. Xia’s research focuses on developing advanced functional nanomaterials and applying them to technologically important applications such as medical diagnostics, bio-/chemical sensing, and food safety and quality management. 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 sensing techniques in biomedicine and food industry by taking advantage of the unique properties of nanomaterials. The ultimate goal is to develop highly sensitive, reliable, and low-cost sensing technologies that are suitable for industrial uses.
