Figure 5. Histogram of dwell time for short 60-mer poly(dA) translocation using 50-nm amine-silica bead-coated substrates.

Translocation events (N = 656) were obtained under the condition that the applied voltage was 1 V (low-pass filtered at 5 kHz). Nanopore diameter and membrane thickness were 2.0 nm and 20 nm, respectively. The distribution was fitted successfully using log-normal distributions.
