Catanionic systems consist of mixtures of cationic and anionic surfactants. We focus more specifically on catanionic vesicles where the bilayer is in the solid-state ("gel-phase"). This allows exploring original, fundamental issues (peculiar morphologies, kinetic blocking, original phase transitions) as well as potential perspectives for encapsulation / vectorization / triggered release.

Osmotically induced deformation of capsid-like icosahedral vesiclesBealle G, Jestin J, Carriere D We have uncovered peculiar buckling transitions in icosahedral catanionic vesicles that trigger the release of any ancapsualted solutes. This provides a better understanding of the unique morphological and mechanical properties of these vesicles. |
In-plane distribution in mixtures of cationic and anionic surfactantsCarriere D, Belloni L, Demé B, Dubois M, Vautrin C, Meister A, Zemb T Combining small-angle neutron scattering and Monte-Carlo simulations, we have shown that catanionic bilayers present a nanometric-range order, but no superstructures, even at the preferential ratios that we have evidenced previously. |
Fatty acid-cationic surfactant vesicles: counter-ion self-encapsulationKopetzki D, Michina Y, Gustavsson T, Carriere D We have shown that the build-up of catanionic vesicles with solid-state bilayers ("gel-phase") is accompanied by what we have named the "self-encapsulation" of the counter-ions in the aqueous core. This leads to the spontanous formation of a transmembrane pH/salt gradient. |
