(a) The intensity distribution profile cut along the lateral direction at the first-order Bragg peak position for DPPC multibilayers inserted with β-amyloid peptide 1–40 at 93.66% relative humidity at 306 K. The solid line is the fitting of the diffuse structure profile according to a form factor corresponding to cylinders sitting vertically in the bilayer. (b) The intensity distribution profiles cut along the lateral direction at the first-order Bragg peak position for DPPC multibilayers inserted with β-amyloid peptide 1–40 under higher relative humidity at 306 K. The inset shows the development of the hump as the relative humidity increases. |
