    Research output: Contribution to conferencePaperpeer-review


    A method, which is called as "nanofishing," enables us to stretch a single polymer chain with picking it at its two modified termini using atomic force microscopy (AFM). Stress-strain curves obtained to data had been the result of slow pulling speeds and therefore observed phenomena had been interpreted as quasi-static responses. In this study, we extended the capability of nanofishing to the phenomena far from equilibrium state by giving much faster pulling speeds. We also measured the dynamic sinusoidal response, as in macroscopic Rheological studies, repeatedly at several extension lengths before full stretching or rupturing. The Rheological properties of a single polymer chain were discussed from the frequency-dependent measurement.
