FIG. 2.
Forces, F, measured with the SFA between mica-supported gel-phase DPPC bilayers in DMSO–water and glycerol–water mixtures at 22 °C and pH 6.0 ± 0.2. Solid, colored lines were drawn by hand. (a) Static measurements of repulsive forces on a semilog plot. (b) Adhesion forces measured upon slow separation of the surfaces. Measurements were made at XDMSO and Xglycerol values of 0, 0.02, 0.05, and 0.075, and the trends were consistent, but due to overlap between force curves, only certain data series are shown here for clarity.
