Two approaches in the preparation of coated liposomes are employed: the copolymer is added during (“in prep”) or after (“ex post”) the liposome formation. The influence of polymer concentration and coating method is evaluated using the cryogenic transmission electron microscopy, dynamic light scattering, and small-angle X-ray scattering techniques. The in prep modification significantly increases, up to four weeks, the stability of liposomes against aggregation and makes the liposomal membrane nonpermeable toward an inorganic salt. Such enhanced longevity is attributed to the different structure of in prep coated liposomal membranes.
