(a) Sketch demonstrating the loss of orientational entropy following the formation of a bridge. (b) Sketch of the effective patch area for bridge formation . (c) Comparison between the contact-angle dependence of and A_p: the latter decays to zero for . (d) Translational entropy loss for bridge (black) and loop (red) formation (equation 9) and rotational entropy loss (blue, equation 8). (e) Fraction of bound tethers: Experimental estimates of x_b (symbols) and theoretical prediction for the fraction of bridges (x_b, solid line) and loops (x_l, dashed line). Shaded regions indicate the error bars of the model propagated independently from uncertainties in α (light blue), K_a (light green) and combining those from ΔH⁰, ΔS⁰ and ρ_DNA (pink). The model parameters are given in Table 1. Exp. ves. 1/2, experimental data for vesicle 1/2. (f) Snapshot of a pair of adhering DNA-GUVs. The shaded regions are used to estimate the average fluorescent intensity of the adhering (green) and non-adhering (red) portions of the GUVs. Scale bar, 10 μm.
