On Friday, Sept. 5 at 11:00 am, in salle de conférences ISM (bâtiment A12), Prof. Peng Chen (Cornell University) will give a lecture entitled:
"Single-molecule chemistry: from molecular adsorption to bacterial extracellular electron transfer"
This presentation will have two parts on using single-molecule approaches to study foundamental chemical and biological processes. In part 1, I will describe our efforts in developing and applying single-molecule super-resolution imaging approaches to study catalysis and molecular adsorption on nano/micro-scale catalyst particles, focusing on our recent work of imaging nonfluorescent surface processes, especially molecular adsorption. In part 2, I will present our work in using multi-modal imaging methods to study how membrane electron transfer proteins spatially reorganize and form biomolecular condensates to mediate extracellular electron transfer in bacteria.
