Bioinspired polymeric biomaterials with excellent cytocompatibility have been designed in this study. 2- Methacryloyloxyehtyl phosphorylcholine (MPC) is a phospholipid polymer and an essential polymeric biomaterial, which has been used in various biomedical and pharmaceutical applications including implantable medical devices. Furthermore, it is a methacrylate monomer unit and can be copolymerized with other vinyl monomers via conventional radical polymerization. The water-solubility of MPC polymers depends on the molecular composition and molecular weight of the polymers. PMB is a water-soluble polymer copolymerized with hydrophobic n-butyl methacrylate, and can be used as a solubilizing agent for poorly soluble drugs. The phospholipid polymers showed low cytotoxicity, and the solubilized drugs effectively not only penetrated into the cells but also into the surrounding tissues. In addition, the water-soluble MPC polymer containing a phenylboronic acid moiety was observed to spontaneously form polymeric hydrogels with polyol compounds. The reversible polymer hydrogels were used as artificial extracellular matrices for cell immobilization and cell engineering. Polymeric biomaterials with intelligent interfaces might be explored as innovative techniques for application in pharmaceutical and life sciences.
