Fig. 9. Various scaling exponents with length for DNA translocation through nanopores.

Fig. 9

(a) Mean velocity of poly(dA)N translocation through α-hemolysin is constant for N > 12 (recorded at 2 °C and 120 mV) [51]. Inset shows a typical, asymmetric dwell-time distribution. (b) Mean dwell time vs. DNA length for dsDNA through a 10 nm SiO2 pore (recorded at 21 °C and 120 mV) [47,55]. Inset shows log-normal distributions for different DNA lengths. (c) Mean dwell time vs. DNA length for dsDNA through a 4 nm diameter pore (recorded at 21 °C and 300 mV) [52]. Cartoons illustrate the possible interactions that lead to the transition from t1- to t2-dominated dynamics. Images obtained with permissions from the publishers.
