AFM setup and tissue imaging. (A) AFM consists of four important components – cantilever with an AFM tip, laser diode, position-sensitive photodetector, and xyz-piezo scanner. (B) Height and deflection images show the decellularized dermal matrix which shows the collagen fibers running along other matrix components (Rianna et al., 2018). (C) Deflection (nm) vs. Z height (μm) shows the approach and retract curve (Viji Babu et al., 2018). (D) Force maps show the elastic modulus values of mouse skin tissue in a respective color scale (Pa) (Joshi et al., 2017).
