AFM images of Aβ(1–42) solutions incubated in the presence of Cu2+ for 0 (A), 12 (B) and 168 h (C) and in the absence of Cu2+ for 0 (D), 12 (E) and 96 h (F). The incubation temperature was 25 °C and pH was 6.6. The scale bars in all images correspond to 400 nm. Aβ(1–42) concentrations in both the Cu2+ (25 μM)-containing and Cu2+-free solutions were the same (25 μM)
