SANS spectra for 20 mg/mL, 50 nm in diameter small unilamellar vesicles of a 1:1 mixture of tail-deuterated DPPC (dDPPC) and DLPC at different temperatures. The solvent matches the mean SLD of the vesicles at high temperature (40.6 °C) when no domains are present. At lower temperatures, excess scattering appears due to the emergence of solidus and liquidus domains, which unequally partition deuterated and non-deuterated lipids, creating contrast between regions within the membrane as well as the solvent.
