%X In this study, we describe the miscibility of four azide-modified membrane phospholipids (azidolipids) with conventional phospholipids. The azidolipids bear an azide group at different positions of the sn-1 or sn-2 alkyl chain and they further differ in the type of linkage (ester vs ether) of the sn-2 alkyl chain. Investigations regarding the miscibility of the azidolipids with bilayer-forming phosphatidylcholines will evaluate lipid mixtures that are suitable for the production of stable azidolipid-doped liposomes. These vesicles then serve as model membranes for the incorporation of model peptides or proteins in the future. The miscibility of both types of phospholipids was studied by calorimetric assays, electron microscopy, small-angle X-ray scattering, infrared spectroscopy, and dynamic light scattering to provide a complete biophysical characterization of the mixed systems.
