(A) Time series for a pivoting particle (i.e., bound to the surface at a single point). The corresponding potential is shown in Fig. 1. Here, hmax ≈ 25 nm. The conditions are PBS/6, pH 7.4. (B) Time series for a pivoting particle. Upward fluctuations are suppressed by the constraint (h ≤ hmax ) imposed by the pivot. In this case, hmax ≈ 14 nm. Conditions are otherwise the same as in A. (C) The interaction potential corresponding to B. The cutoff h ≤ hmax is evident; hmax ≈ 14 nm. Also shown is the (unconstrained) DLVO potential (dashed line).
