Influence of Halide Solutions on Collagen Networks: Measurements of Physical Properties by Atomic Force Microscopy

Figure 2

Topographical image of collagen tissue with local valley detection results marked in yellow; 2 μm × 2 μm image size; white line in (a) showing position of height profile; white box in (b) showing position of detailed profile. Local valley radius: (a) 10 nm/(b) 20 nm. Bottom left: height profile with exaggerated height values along the white line shown in top images. Bottom right: height profile section from the white box situated in one of the most extreme topographical pattern situations of the image and showing true proportions; herein depictions of sensor apexes with radiuses 10 nm and 20 nm in true dimensions and positioned at the average indentation depth measured.
