AbstractLiposomes are macromolecular structures in which an aqueous core is surrounded by a double-layered lipid membrane. Surface modifications in liposomes serve the purpose of enhanced water-solubility, immuno-compatibility, and targeted delivery of liposome “cargo”, e.g. drugs or DNA/RNA. Liposomal drug delivery systems are frequently composed of phospho-lipids and ceramides amongst others. We investigated pH-sensitive liposomes. Complete NMR structure assignment and quantification of all components provided quality control. During liposome extrusion/preparation/loading and cleanup, little to no variation in composition was observed.
