Fig. 1. (a) Surface pressure-area isotherms of PE : PG 80 : 20 (solid cyan line), PE : CL 95 : 5 (dashed grey line) and PE : PG : CL 80 : 15 : 5 (dash-dotted orange line). Barrier speed 25 cm2 min−1, temperature 19.5 °C. The inset shows the corresponding compressibility moduli. (b) Lc–S (filled shapes) and Le–Lc (open shapes) phase transition pressures vs. mol fraction anionic lipid. Pink squares PG, teal triangles CL.
