| Abstract: | Hybrid bilayer vesicles were formed by combination of dimyristylphosphatidylethanolamine as a lipid signal and a cationic synthetic lipid as a matrix.The sonication condition for preparing the hybrid bilayer vesicles was discussed.The aggregate morphology was confirmed by means of transmission electron microscopy and dynamic light scatting measurements,and the vesicles showed a phase transition from gel to liquid-crystalline state at 31.2(C as evaluated with differential scanning calorimetry. |
