Self-assembly lipid/protein cubosomic nanostructures are generated at high hydration level (dispersion of 5% lipid only) and examined by freeze-fracture electron microscopy (FF-EM) and synchrotron X-ray diffraction (XRD). The fracture surface of the three-dimensional (3D) soft-matter membranous assembly reveals starlike nanopatterns of oriented 100-nm-long cubosomic nanoridges with lateral periodicity defined by their 21-nm diameters. The average water channel radius in these liquid crystalline cubosomic nanoarchitectures, determined by high-resolution FF-EM and XRD, is 18.0 Angstrom. The protein-directed fragmentation of a diamond-type lipid cubic phase at high hydration can induce 3D patterns of oriented nanoporous building blocks, which are a unique example of tertiary organization of functionalized fluid lipid/water interfaces.
