DSPE phospholipids as pharmaceutical excipients have the functions of emulsification and drug solubilization. In recent years, DSPE phospholipids are important materials for slow and controlled-release drug preparations such as liposomes, fat emulsions and nanoparticles. The modification of phospholipid molecules can make these preparations have the ability to release and target under specific conditions.

The common modification methods include: introducing polymer to improve the blood circulation time and disintegration time of the preparation; Introducing immune factors to enhance targeting; Introduce markers for diagnosis and tracking. Among them, polyethylene glycol (PEG) is Zui commonly used to improve the properties of phospholipids, and its end can be further modified to connect peptides, nucleic acids and other ligands, so that PEG phospholipid carrier has immune targeting. The application in slow-release and controlled-release preparations such as immunoliposomes is the research hotspot of targeted drugs. We call this kind of phospholipids functional peg phospholipids.
