LIPID MEMBRANE STRUCTURE, LIPID MEMBRANE STRUCTURE PRODUCTION METHOD, AND METHOD FOR ENCAPSULATING ONE OF THE TARGET SUBSTANCE WITH A SINGLE LIPID MEMBRANE

摘要

[Problem] To provide lipid membrane structures that can be easily produced, are small and have a uniform particle diameter, lipid membrane structures wherein the number of the encapsulated substance (target substance) and the number of lipid membranes are controlled, a production method therefor as well as a method for encapsulating one of the target substance with a single lipid membrane. [Solution] A lipid membrane structure having a lipid membrane modified with a cationic surfactant as a single membrane or as the outermost membrane of multiple membranes. Using lipid membrane structures of the invention or the production method therefor makes it possible to obtain small and uniform lipid membrane structures and lipid membrane structures wherein the number of the encapsulated substance (target substance) and the number of lipid membranes are controlled.
