Colloidal semiconductor nanocrystals (quantum dots) have attracted great attention for their distinguished roles in fundamental studies and technical applications such as biological labeling and optoelectronic devices. In the last decade, the main efforts have been focused on the preparation of size-tunable binary or core-shell nanocrystals with different emission colors. In our research, we also focus on the development of highly luminescent composition-tunable quantum dots across the whole visible spectrum. The resulting high-quality size- and composition-tunable quantum dots have been successfully used as multicolor biological nanoprobes for imaging, sensing, and drug delivery applications.

Dr Han Ming-Yong holds a joint appointment with the Institute of Materials Research & Engineering and National University of Singapore. His research interests are to develop functional nanomaterials and multi-color biological nanoprobes for biomedical and optoelectronic applications. He has published more than 70 peer-reviewed papers in the field of functional nanostructured materials/nano-biotechnology. His papers have been cited more than 3,000 times, and received more than 60 news/comments from Nature, Nature Biotechnology, Nature Asia Materials, Scientific American, Chemical & Engineering News, The New York Times, etc. He also holds 20 patents or patent applications.
