    Herein, we report an optical nanopore detection system capable of investigating DNA motion near nanopores not only during translocation but also post-translocation with submillisecond resolution. Using our optical nanopore detection system, we observed the voltage dependence of the dwell time of both 10-kbp double-stranded DNA (dsDNA) and lambda DNA in the excitation volume, which can be attributed to the drift-dominated motion. We found that the lambda DNA had slower drift motion than 10-kbp dsDNA, indicating that DNA with longer gyration experiences a lower nonuniform electric force.
