FIGURE 3.

AFM topography images showing the expansion of DOPC fluid-phase bilayer during heating. DOPC bilayer was formed from buffer solution by applying 70 μL of 0.5 mg/mL onto freshly cleaved pure mica for 30 min, then the cell was rinsed and covered with nanopure water. The images shown are after: (a) heating to 50°C; (b) 1 h scanning at 50°C; and (c) cooling to 45°C.
