Nanoindentation deformation results for different biological fibrils. (a) Force as a function of the indentation depth (h) for α-syn, three Aβ₄₀, and two Aβ₄₂ fibrils. Square symbols refer to v_ind = 0.005 Å/τ and R_ind = 10 nm. The error bars are the same as the symbol size and they are based on 50 independent simulations for each system. The distributions are calculated for h = 0 (solid line) and h = 20 AA in the case of α-syn fibrils and Aβ fibrils (dashed lines). Only in the case of Aβ₄₂ with PDB ID: 2NAO the value h = 9 Å was considered.
