Discretized distribution functions, f(r), of the radial positions of individual coarse-grained beads in a channel at λD = 0.3, 5, and 15 nm, for (a and b) a negative ζ-potential of −25 mV and polymer lengths of (a) N = 5 and (b) 50, and for (c and d) a positive ζ-potential of 25 mV and (c) N = 5 and (d) 50. The radial position of each molecule was sampled at 10 μs intervals over the last 1.0 ms of simulation time. To see this figure in color, go online.
