Аннотация:The adsorption of anionic lipid vesicles (liposomes) on the surfaces of colloidal particles containing grafted polycationic chains (cationic brushes) is studied. The stability of liposome-brush complexes in aqueous salt solutions increases with the content of anionic lipid in the liposomal membrane; complexes with liposomes containing 20 and 30 mol% anionic lipids do not dissociate into individual components in a 1.2 M NaCl solution. The integrity of the brush-bound liposomes is preserved. The developed approach can be used to obtain nanosized carriers for biologically active compounds.
