ToF-SIMS images showing the effect of cholesterol on the lateral organization of DPPC and DPPG in BLES LB films. BLES was supplemented with 20 mol% cholesterol and a film was compressed to a surface pressure of 30 mN/m and transferred onto gold-coated mica by conventional Langmuir–Blodgett technique. Image A was collected in positive ion mode and shows the distribution of M735 (DPPC-H+) and image B was collected in negative ion mode and shows the distribution of M722 (DPPG−). Both images are 50×50 μm2, 256×256 pixels with 1 shot/pixel.
