This presentation will describe our efforts in developing and applying single-molecule manipulation and imaging approaches to study living polymerization reactions of single polymer chains down to single-monomer resolution. In the first part, I will describe our work in using magnetic tweezers to track single polymer growth in real time and the discovery of nonequilibrium conformational entanglements that play key roles in controlling polymerization kinetics. In the second part, I will describe a new fluorescence-based imaging technique that enables following polymerization of individual polymers at single-monomer resolution, leading to microscopic sequencing of synthetic copolymers and discovery of copolymer sequence patterns.
