Fig. 2. (A) Representative AFM image (5 × 5 μm) of the Cu-3G/PLL/phosphate composite layers; (B) 3D view of the same area; (C) profilometric section of the AFM image; (D)–(F) the same images for the Cu-2GH/PAH/phosphate LbL formations. Eight deposition cycles were conducted in both cases according to method (A) at pH = 10. The places of profilometric cross-sections are indicated by white lines in (A) and (D).
