Figure Lengend Snippet: Structural characterization of the AgNPs-based biomaterials. (a, b) SEM top-view images at two resolution scales, (c) histogram showing results from statistics performed on 222 AgNPs: size distribution by bins and the corresponding Gaussian distribution function, (d) AFM topography image of the sample surface, including the arithmetic and quadratic surface height parameters, (e) AFM surface topography profile along 6 AgNPs, as marked with the white line on the topography image, and (f) extracted high order surface height parameters (skewness and kurtosis) of the studied area.

Figure Lengend Snippet: AFM topography images, in tapping mode, of 72h-old biofilm formed on SiO 2 -samples in 3D (6 μm × 6 μm) in (a) and 2D (32 μm × 32 μm) in (b) representations. The respective heights and occurrences are shown in (c) and (d). The displayed height profile in (c) was determined along the white dashed line shown in (b) The occurrence diagram in (d) was determined over the entire topography map in (b).

Figure Lengend Snippet: AFM topography images, in tapping mode, of AgNPs-based biomaterials after 72h of dynamic culture in 3D (1.6 μm × 1.6 μm) on (a) and 2D (1.6 μm × 1.6 μm) on (b) representations; the height color bar is common for the two representations, in (a) and (b). Magnification (425 nm × 425 nm) of the dashed square on (b), representing the remaining AgNPs (some of the AgNPs are suggested by the white dashed circles) is given on (c).
