A novel biosensor with high sensitivity for the electrochemical detection of benzylpenicillin wassuccessfully constructed by immobilizing β-Lactamase on a fullerene (C60) supported bilayer lipidmembrane (C60-s-BLM) modified gold electrode (GE). β-Lactamase was well immobilized on theelectrode surface because of the good biocompatibility of the BLM. C60 was used as an electron transferenhancer and an efficient immobilization matrix for the sensitivity enhancement. Transmission electronmicroscope (TEM) and cyclic voltammetry (CV) were used to characterize the surface morphology andthe catalytic performance of the electrode, respectively. The results showed that the sensor had a goodlinearity in the range of 1.9-223.3 ng/L and a detection limit of 0.6 ng/L..
