DOPE-PEG-COOH sodium salt contains a terminal carboxyl group on a PEGylated DOPE scaffold, enabling covalent attachment of amine-containing biomolecules via carbodiimide chemistry. The hydrophilic PEG spacer ensures accessibility and minimizes nonspecific adsorption, while the DOPE moiety promotes stable bilayer insertion and curvature modulation. This functional lipid is widely applied in customizing liposome surfaces, preparing bioresponsive membrane constructs, and engineering lipid–polymer hybrid systems. Its sodium salt form enhances solubility and handling in aqueous formulations, making it ideal for precision surface chemistry and biomimetic nanomaterial development.
