Single-molecule Catalysis: Nanoparticles and Polymers

Speaker: Peng Chen, Cornell University

Host: YuHuang Wang

Abstract: This presentation will describe our efforts in developing and applying single-molecule approaches to study (photo)(electro)catalysis on nanoparticles and in making polymers. In the first part, I will give some background on single-molecule, super-resolution fluorescence imaging of catalytic reactions on single nanoparticle, with some examples, as well as present our recent work of imaging nonfluorescent surface processes at super optical resolution. In the second part, I will describe our work in using magnetic tweezers to track single polymer growth in real time under living polymerization catalysis conditions.
