DSPE-PEG2-Mal functions as a polymer that can self-assemble to form lipid bilayer in water. The phospholipid polyPEG can be used as a drug nanocarrier for administration of nutrients and therapeutic drugs, such as liposome in mRNA or DNA vaccines. The maleimide group will react with a thiol group to form a covalent bond. The PEG2 units bolster hydrophilicity.
