Fig. 2. (A) AFM height images of β-LG11–20 fibrils formed at 50 °C and pH 2 (after 96 hours). Images were collected in air. The right side shows the profiles with different periodicity that are highlighted in the left side image. (B and C) AFM height images of β-LG11–20 displaying a mesh-like (B) and web-like (C) structure in areas with a high fibril density. (D and E) Statistical AFM analysis of fibril morphologies. The periodicity distribution showing that the majority of formed fibrils have periodicity of 35 ± 5 nm (D) and the correlation between periodicity and fibril heights (E).
