FIGURE 6

Configuration of a small regular brush made of 13 molecules. The distance between two adjacent molecules is 7σ (i.e., position of No. 1 = (0, 0), No. 2 = (−3.5σ, 6.056σ), No. 10 = (10.5σ, 6.056σ), etc.). The time spent in contact with the primers is 1.6(2)% for the molecule at the center of the colony, 2.5(2)% for the “core” molecules (Nos. 2–7), and 3.4(2)% for the molecules on the perimeter (Nos. 8–13). The average contact distances are 〈h〉 = 7.3(2) for the central molecule, 〈h〉 = 8.5(2) for the “core” molecules, and 〈h〉 = 8.5(2) for the molecules on the perimeter.
