Figure 6
(a) Comparison of $[\kappa_{\rm NSE}]$ values obtained from unilamellar (

) and slightly multilamellar (

) DOPC vesicles; the Bragg peak corresponding to the lamellar spacing at $[q\approx 0.1]$ Å⁻¹ leads to higher apparent bending rigidities at the peak position. The dashed lines correspond to the calculated value of $[\tilde{\kappa}]$ for DOPC using values of κ, $[K_{\rm A}]$ and $[d_{\rm c}]$ reported for DOPC by Pan et al. (2008

). (b) Corresponding SANS data normalized by the lipid mass fraction ( $[c_{\rm L}]$ ) (MLVs from D11, ULVs from D22). The multilamellarity is not immediately obvious in a plot of intensity versus q. MLV data are adapted from Alvarado Galindo et al. (2024

). Error bars represent one standard deviation.
