Figure 2. SEM images of gold nanoparticles synthesized in situ in (PLL9.5/HA2.9)7-PLL9.5 films: surface morphology at different magnifications (left and middle columns) and cross-sections (right column).

Figure 2

Gold chloride was loaded at pH 3 (A-A”), 6 (B-B”), and 9 (C-C”). The scale bars are 30 μm for (A, B, C) and 2 μm for (A’, B’, C’).
