(a) SAXS data (from top down) of the three types of Pristine-18, -20 and -22 liposomes, fitted (solid curves with the best-fitted χ2 indicated) using the five-layered model. The first two scattering intensity profiles are, respectively, scaled up by a factor of 100 and 10 for clarity in visualization. Note that the not-small χ2 values are consequences of fitting the data of small error bars, having a high χ2 penalty in more sensitively differentiating parameter values. (b) The corresponding best-fitted Gaussian ED profiles, with Z = 0 set as the center of the middle layer for the aliphatic chains in the five-layered model and Δρ for the electron density difference with respect to that (0.335 e− Å3) of water. Also shown in (a) is an improved fitting (dotted curve) using (c) the SLD profile of the core–multishell model (CMS) for the Pristine-22 liposomes, with a core radius of 37.7 nm. The five shells are indicated by numbers in (c).
