报告题目:Graphene Quantum Dots for Bio-imaging and Optical Sensing

报告人:Peng Chen, Professor

Biography: Professor Chen Peng obtained his bachelor’s and Master’s degrees from Zhejiang University in China. He completed his Ph.D. study in University of Missouri at Columbia in 2002. After a period of post-doctoral training at Harvard University, he joined Nanyang Technological University (Singapore) as an Assistant Professor in 2005. Currently, he is a full professor of Bioengineering in the School of Chemical & Biomedical Engineering. Professor Chen’s research focuses on nanomaterials (particularly, graphene materials) and their applications in biosensing, bioimaging, and energy devices. His research has resulted in a number of patents and >150 publications in reputable journals, such as, ACS Nano, Nano Letters, Advanced Materials, Angewandte Chemie International Edition, which have received >8700 citation counts according to Web of Science.

Abstract: Due to some intrinsic limitations suffered by the current fluorophores (e.g., fluorescent proteins, organic dyes, and semiconductor quantum dots), seeking complementary or better fluorescent reporters is a constantly ongoing effort critical for the areas of bio-imaging, optical sensing, photovoltaics etc. Graphene quantum dots (GQDs or 0D graphene) are atomically-thin and nanometer-wide planar structures of pristine or modified graphitic carbon. They are emerging as a new class of fluorophores with unique combination of several key merits including widely tunable photoluminescence (PL) properties, excellent photostability, molecular size, biocompatibility,and good solubility. GQDs promise a wide range of novel applications in biomedicine, energy storage and conversion, catalysis, etc. In this presentation, we demonstrate the methods to synthesize GQDs and the applications of these GQDs for real-time molecular imaging in live cells, ultrasensitive fluorescence detection of biomolecules, monitoring of dynamic cellular redox homeostasis, and electrochemical detection of heavy metal ions.
