Our research group is interested in addressing fundamental issues in the field of nanoscience and nanotechnology. Currently, our research focuses on nanocrystal synthesis, assembly and surface engineering. First, we are developing a non-injection synthesis for making high-quality nanocrystals based on the understanding of nanocrystal nucleation and growth. This method allows for the production of high-quality nanocrystals at industrial scale and low cost. Second, we are developing synthetic approaches to achieve position-controlled doping of nanocrystals, and understanding the principles to control nanocrystal physical and chemical properties through such doping. Third, we are developing novel approaches for creating a new class of colloidal particles with superlattice structures (i.e., supercrystalline collections of artificial atoms in the form of “superparticles”), and evaluating their photophysical properties for energy conversion. Fourth, we are developing new nanocrystal surface functionalization methods to create powerful tools that can be used in the areas of chemical and biochemical analysis, biomedical diagnosis, and drug delivery.
