Resonance frequency overtones Δf and the energy dissipation overtones ΔD (n = 3rd, 5th, and 7th) over time for (a) C12E2, (b) C12E6, and (c) C12E12 at a concentration of 1 CMC. (d) Surface excess change and birefringence of the model DMPC bilayer during surfactant binding. Cartoon showing the kinetics of (e) C12E2, (f) C12E6, and (g) C12E12 binding with DMPC bilayers.

Article Snippet: DMPC (14:0 PC, 678 g/ mol) and chain deuterated DMPC (dDMPC, 14:0 PC-d54) were purchased from Avanti Lipids (Alabaster, Alabama, USA) and used without further purification.

Figure Lengend Snippet: Figure 1. Schematic of the ternary phase diagram for the lipid membranes of DOPC/DSPC/cholesterol (Chol) at 22 ◦C, based on ref. [13]. Ld, Lo, and Lβ are the liquid- disordered, liquid-ordered, and solid-gel phases, respectively, for the in-plane organization of the membranes. The filled circle is the miscibility critical point. The compositions of the homogeneous and laterally heterogeneous membranes are marked by filled squares and triangles, respectively. Rectangles mark two compositional regimes, (a) and (b), where the fusion extent of the homogeneous membranes behaved distinctly.

Article Snippet: Lipids, DSPC (distearoylphosphatidylcholine or di18:0PC; cat. no. 850365C), DOPC (dioleoylphosphatidylcholine or di18:1PC; cat. no. 850375C) and Chol (cholesterol; cat. no. 700000P), were sourced from Avanti Polar Lipids and used as received.

Figure Lengend Snippet: Figure 3. Electron density profile p(z) transverse a lipid membrane extracted from the fit against Equations (2)−(4) in Figure 2 for (a) the composition of DOPC/DSPC/Chol = 14/44/42 and (b) all the compositions for homogeneous membranes at 23 ◦C. zH marks the position of the headgroups, and 2zH is defined as the membrane thickness. Curves in (b) are vertically shifted for clarity.
