Permeability-induced changes in SANS data for DPPC LUVs at 283 K. (a) Comparison of initial and equilibrium scattering patterns. The first frame was recorded after a dead time of 40 ms. Solid lines represent best fits with equation (7

), differing only in core SLD ( $[\rho_{\rm C}]$ ). (b) Low-q scattering profiles at selected time points, with corresponding fits (solid lines). The dotted line corresponds to the calculated scattering intensity of t₀. The inset displays SLD profiles for each time point.
