Top row: AFM images of the aggregation products obtained after incubation of 10 µM Aβ40 peptides for 24 h together with either 0, 1, 10, or 50 µM Ni(II) acetate. Bottom row: Representative AFM cross-sections of respectively Aβ40 amyloid fibrils (A,B) and Aβ40 unstructured aggregates (C,D), corresponding to the colored lines shown in the AFM images.
