Random Walk Formula
General Modeling IdeaThe random walk on DNA origami can be modeled as one dimensional random walk with a reflecting and an absorbing barrier (Figure 1). Tracks in the same column are grouped into rectangles, and each step is defined as walking from one rectangle to the adjacent one. Various formulae had been developed to model this process, but none of them can perfectly match our situation (Weesakul, 1961; Hardin & Sweet, 1969; Alessandro Blasi, 1976; Ahmed ElShehawy, 1992).
