Figure 4.

AFM scans (5 μm × 5 μm for a–c; 3 μm × 3 μm for d) in tapping mode in buffer P1, with corresponding height profiles, represented as white horizontal lines in each image, below each scan. (a) Membrane formation on a mica surface. (b) A mica surface covered with membrane containing BR. (c) A functionalized glass surface covered with the membrane containing BR. (d) Scratching was performed with the cantilever on a surface functionalized with lipid and protein anchor and incubated with the protein lipid mixture. To see this figure in color, go online.
