Popis: Amphiphilic low-molecular-weight chitosan N-acylated with 3-hydroxytetradecanoic acid was synthesized. It was shown that addition of the acylated chitosan changes the surface potential and size of negatively charged liposomal particles, the magnitudes of which depend on the chitosan concentration. Charge neutralization and aggregation of the liposomes occurs at low chitosan concentration. Increasing its concentration produces positive charge on the surface of the liposomes and decreases their size. This increases the stability of the liposomal particles in solution. Liposomes coated with chitosan may be of interest as carriers for genes, vaccines, and drugs.
