Аннотация:Recently, much attention is paid to the development of nanostructured materials by selfassembly. The report discusses the results of the first simulation of the effect of adding an inorganic salt on the morphology of supramolecular structures in aqueous solution of a mixture of lecithin and bile salts. All calculations were carried out in the framework of the dissipative particle dynamics. Using a parallelized computation performed on the cluster "Lomonosov" of the Supercomputer Center of Moscow State University, allowed to realize the modeling of large enough cells for extended time intervals over a wide range of parameters. We observed the effect of salt on the change in the morphology of aggregates of lecithin and bile salts. Depending on the concentration of salt, we observed transformation of ellipsoidal or cylindrical structures in long worm-like micelles. These long, flexible wormlike micelles can cause the experimentally observed increase in the viscosity of the solution of lecithin.
