Fig. 8 — Neutron spin-echo (NSE) spectroscopy and solid-state ²H NMR relaxometry show nearly identical increases in bending modulus of unsaturated lipid membranes with cholesterol mole fraction. a Electron density (ED) profiles along the membrane normal (z-axis) obtained from SAXS data for DOPC/cholesterol membranes, such that z = 0 denotes the center of the membrane. b NSE-measured intermediate scattering functions on 50-nm vesicles of protiated DOPC membranes with 20 mol% cholesterol. Error bars represent ± 1 standard deviation. The lines are fits to the data using a stretched exponential function. c Relative bending rigidity moduli (κ/κ₀) calculated from nanoscale bending fluctuations sampled by NSE spectroscopy, solid-state ²H NMR relaxometry, and analysis of MD simulations.
