Exemplary processing of AFM images of enzymatic degradation to determine Δh_max. Crystalline fibrils embedded in amorphous cellulose matrix provide time-resolved quantitative data for comparison of simulation results with the experiment. a Height profiles (red line) of crystals were taken from AFM sequences recorded from enzymatic reactions carried out as described by Ganner et al. [14]. For easier viewing, the amplitude image of the corresponding position is shown. The yellow scale bar shows 10 nm. b The highest point on a cellulose crystallite was found by moving the section profile along the crystallite, and the vertical height difference between the highest point and the amorphous material (indicated by the arrow) surrounding the crystallite was calculated (∆h_max)
