| Outline of Final Research Achievements |
Flow-type fabrication method of liposome was developed by using flow state of supercritical carbon dioxide in microfluid system. This flow-type process was extended to the fabrication of PEGylated liposome. It is found that the structured-liposome can be formed in this flow-type process. Size of liposome can be controlled largely using ethanol as solvent for lipid in the flow-type process. Also, the fabrication process of PEGylated liposome in Post-Tube process allows to reduce the particle size of liposome and increase the encapsulation efficiency compared with those by the batch-type process.
