This presentation will discuss how to employ the AFM based single-molecule force spectroscopy (SMFS) to manipulate single polymers and to study their dynamics at the single molecular level, hence promoting significantly the progress of traditional polymers science and opening many new horizons for the future. On one hand, we will introduce the use of SMFS for studying various intermolecular interactions, such as pi-pi interaction between pyrene and graphite and intercalation interaction between DNA and acridine, leading to understanding the non-covalent bond and driving forces for molecular assembly. On the other hand, SMFS also allows for manipulating single chain of stimulus-responsive polymers, such as poly(ferroncenylsilane) (PFS). By using the special feature of the PFS that can be extended upon oxidation and retracted upon reduction, we are able to realize a single macromolecular motor with a maximum efficiency of 26%.
