Application

PEG-b-PMPC is a biocompatible, non-fouling block copolymer composed of a neutral PEG block and a zwitterionic poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) block.


Poly (2-Methacryloyloxyethyl phosphorylcholine) (PMPC) is a methacrylate based polymer with a zwitterionic phosphorylcholine moiety on the side chain. The phosphorylcholine moiety is very similar to the head group of phospholipids in cell membranes. Due to this unique structure, PMPC showed excellent resistance to nonspecific protein adsorption, cell adhesion, and blood coagulation, as well as cell membrane penetration and underwater lubrication.


PMPC has been widely exploited in a diverse range of applications including
  • antifouling materials for water treatment
  • bioengineering
  • nanomedicine

The water-soluble, biocompatible polymer poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) was evaluated for protein conjugation. PMPC is a zwitterionic polymer that is able to form a more compact conformation in aqueous solution than poly(ethylene glycol) (PEG).
