(a) The intensity distribution profiles cut along the lateral direction at the first-order Bragg peak position for a pure DPPC film under different relative humidities at 306 K. The cut lines are shown in Fig. 1. (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 different relative humidities at 306 K. The cut lines are shown in Fig. 4. |
