Biocompatibility is indispensable to biosensors for in vivo purpose. To those for in vitro applications biocompatibility can also promote their stability and life time. 2-Methacryloyloxyethyl phosphorylcholine, abbreviated as MPC, is an inert biocompatible material. Biocompatible membranes with special functions including diffusion-limiting effect, selective permeability, and the capability of immobilizing enzymes were obtainable by the copolymerization of MPC with other monomers. These membranes were applied to fabricate needle-type glucose sensors. The sensors were conferred with a wide workable range, good biocompatibility, remarkable long-term stability, and the ability of curtailing interfering responses upon application of these specially functionalized biocompatible membranes.
