Figure 2

(A–C) AFM images of DPPC multilamellar lipid bilayers formed on a Ge IRE surface. (A) Partially fused DPPC multilamellar lipid bilayer at 23°C, before heating. (B) Fluid state DPPC multilamellar lipid bilayer at 52°C. (C) Gel state DPPC multilayer after cooling to 23°C. All images are shown on the same vertical scale for comparison purposes. (D–F) Simultaneously acquired ATR-FTIR spectra of the CH2 symmetric ∼2850 cm−1, and antisymmetric ∼2920 cm−1 stretching modes are shown below their corresponding AFM images. Scale bar: 0.03 absorbance units.
