Dwell time histograms at applied voltages of (a) 100 mV (b) 300 mV (c) 500 mV. Each distribution is fitted with a bi-exponential function (black line) with two time constants, t1 and t2, indicating the two types of polymer transport, fast translocation governed by polymer hydrodynamics and slow translocation regulated by polymer-pore interactions (Insets) Blockage Ratio (Br) vs. Dwell time (tD) [ms] at these respective voltages. Color bar represents number of events. At higher voltages, a greater percentage of events exhibit fast translocation dynamics bounded by the arrows in the insets. Translocation events exhibit clear voltage dependence.
