The study has been performed on model systems of biological membranes obtained on the basis of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) and cationic gemini surfactant - derivative of 1,1'-(1,4-butane)bis 3-alkyloxymethylimidazolium chlorides with cyclic chains. The small angle X-ray scattering SAXS results implied a gradual disappearance (as a function of surfactant concentration) of the lamellar phase typical of DMPC and formation of unilamellar phase - probably a bicellar phase.
