| Abstract: | A goal across multiple scientific fields (e.g. separations, polymer processing, and biomaterials) is to understand polymer dynamics at solid/liquid interfaces. In the last two decades, rapid developments in single-molecule techniques have revolutionized our ability to directly observe molecular behaviors with ultra-high spatial/temporal resolution and to decouple the elementary processes that were often veiled in ensemble experiments. This review provided an overview of principle and realization of two single-molecule fluorescence techniques that were often used to study the interfacial dynamics. In addition, this review updated recent progress in the discovery and understanding of dynamical anomalies of polymers at solid/liquid interfaces using these single-molecule techniques, emphasizing important elementary processes of diffusion, adsorption, and desorption. |
