초록
Nanofishing enabled us to stretch a single polymer chain with picking it at its two modified termini using atomic force microscope (AFM). Stress-strain curves obtained to date had been the result on slow pulling events 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 could observe a momental increase entanglement and a successive stress relaxation.
