pH pH-sensitive vesicle of surface-modified ion pair of cationic polymer and fatty acid

摘要

The present invention relates to a pH-responsive vesicle in which a phospholipid vesicle surface is modified with an ion pair of a cationic polymer and a fatty acid, and a preparation method thereof. The pH-responsive endoplasmic reticulum of the present invention comprises It is stable at a neutral pH to release comparatively less of the loaded contents, and is destabilized in acidity and basicity to exert an effect of relatively releasing the loaded contents.
