Effect of glycol chitosan on functional and structural properties of anionic liposomes

Resumo

The possibility of using glycol chitosan to obtain stabilized liposome containers for doxorubicin delivery is demonstrated. The dissociation constants of the liposome complexes with glycol chitosan (3.4 × 10^–4 and 1.10 × 10^–5 depending on the aggregation state of the liposomes) are determined. It is shown that the formation of liposome complexes with glycol chitosan has a significant prolongation effect on the release of doxorubicin from the liposomes at pH 7.4.
