Abstract

We have used two ways to control the physicochemical properties of liposomal nanocontainers for the delivery of fluoroquinolones: variation of the lipid composition of liposomes and selection of a functionalizing polymer based on chitosan mannose derivatives. The presence of anionic phospholipid cardiolipin in the liposome composition increases the loading efficiency by 5-20%. The mechanism of drug incorporation into membranes was studied, and the main binding sites were determined. The functionalization of the liposomal surface was carried out by chitosan mannose derivatives of various molecular weights, potentially providing targeted delivery to alveolar macrophages.
