Edge-edge attractions in surfactant nanodiscs: Implications

► Concept of edge-edge attractions in nanodiscs induced by hydrophobic interaction. ► Explanation of surfactant segregation within catanionic nanodiscs. ► Explanation of crystalline nature of faces of catanionic nanodiscs. ► Vesicle-to-micelle transition induced by addition of single tail surfactants. ► Explanation for formation of non-spherical micelles in double-chained surfactants.
