Fig. 5From: Evaluating effect of metallic ions on aggregation behavior of β-amyloid peptides by atomic force microscope and surface-enhanced Raman ScatteringAverage particle size of Aβ42 monolayer in the absence and presence of metallic ions (Zn2+, Ca2+ and Al3+) at different incubation time points. All experiments were performed ten times (n = 10). ***P < 0.001, **P < 0.005 vs. control; #P < 0.01 vs. PBS + Zn2+; &&P < 0.005 vs. PBS + Ca2+Back to article page
