Self-organising structures of lecithin

Abstract

Modern concepts of the self-assembly of amphiphiles are considered on the example of self-organising structures of the natural lecithin. Binary, ternary and multicomponent systems are discussed. A considerable part of the review is devoted to the peculiarities of self-organisation of this phospholipid in non-aqueous media and to the role of polar inorganic solvents. Virtually all of the structures formed by lecithin are examined: micelles, swollen micelles, microemulsions, emulsions, organogels, vesicles (liposomes), and lyotropic liquid crystals. In each specific case, attention is drawn to the dependence of self-assembly at the macroscopic level on interactions at the molecular level, shape of molecules, and their solvation and packing at the interface. The self-organising lecithin structures formed in the interfacial area of immiscible liquids in the course of unrestricted adsorption from the bulk of non-aqueous solution are considered.
