Chemical biology is a scientific discipline spanning the fields of chemistry, biology and physics. It is a new and exciting field, which often involves the application of chemical tools to study and manipulate the biological systems. This international symposium will bring together leading experts in chemical biology from UK, Germany, USA, Korea, Canada, and China. The symposium is supported by the National Natural Science Foundation of China (NSFC) and the Royal Society of Chemistry (RSC), and is hosted by the College of Chemistry and Molecular Engineering at Peking University.
