ToF-SIMS (A–C) and AFM (D) images of a 50:30:20 d4-DPPC:POPC:d31-POPG film compressed to a surface pressure of 30 mN/m and transferred onto gold-coated mica (A–C) and freshly cleaved mica (D) by conventional Langmuir–Blodgett deposition. Maps of positive SI showing fragment ions M50 (A), M184 (B) and M188 (C) specific to d31-POPG, POPC and d4-DPPC, respectively. All ToF-SIMS images are 50×50 μm2, 256×256 pixels with 1 shot/pixel. AFM image is 60×60 μm2 and the high magnification AFM image inserted shows a zoomed-in view of the area indicated by the black box.
