(DSPE) polyethyleneglycol is a combination of phospholipid and polyethylene glycol,which has hydrophilicity and hydrophobicity.Polyethylene glycol liposomes were used to form high-quality materials.It can be used for drug delivery,gene transfection and vaccine delivery.Pegylated phospholipids can significantly improve blood circulation time and stabilize drug encapsulation.These materials can also be used for targeted drug delivery by modifying the ligand with the target surface to add antibodies and peptides.
