Primitive and double diamond cubic phases commonly found in cubosomes. A, example Cryo TEM and Fourier transform of cubosomes. B & C, reconstructed 3D image of cubosome from cryo-TEM tomography data showing the lipid arrangement (B) and the water channels (C). D, primitive phase reduced SAXS scattering pattern.[58] E, 2D SAXS scattering pattern[58] corresponding to D and illustration of the primitive cubic phase[45] showing the lipid membrane (grey) and the water channels (blue, orange). F, double diamond cubic phase reduced SAXS scattering pattern.[58] G, 2D SAXS scattering pattern[58] corresponding to F and illustration of the double diamond bicontinuous cubic phase[45] showing the lipid membrane (grey) and the water channels (blue, orange).
