Figure 4.
Integrated GIXD data showing the Qxy-dependence of the in plane scattering of the three amphiphiles at a surface pressure of Π = 40 mN/m. The line displays a fit to a power-law reflecting the diffuse scattering characterizing the capillary wave fluctuations. Note that a predominant peak is visible for the α-helical forming peptide-conjugates but not for scrambled dC16-SC(PEG2k).
