Fig. 9From: FC_analysis: a tool for investigating atomic force microscopy maps of force curvesFC map acquired onto a section of mussel’s glands, embedded in epoxy resin: topographical (512 × 512 pts) image and corresponding (128 × 128 pts) stiffness map acquired in the highlighted region. The white arrows indicates areas with very high local stiffness, which suggests the presence of non-biological material. Data collected with the FlexAFMBack to article page
