In this paper, we describe the preparation of electrochemical glucose sensors based on the glucose oxidase (GOx), which is immobilized into multi-wall carbon nano-tubes (MWCNTs) doped polypyrrole (PPY) membrane during electropolymerization of polypyrrole film. The morphology of the MWCNTs doped polypyrrole film was characterized by scanning electron microscopy (SEM). Glucose is detected by using electrochemical impedance spectroscopy (EIS). An increase in the glucose concentration results in a decrease in the faradic charge transfer resistance (R CT ) obtained from the EIS measurements. The results indicate that the electroanalytical PPY/MWCNTs-GOx film was highly sensitive and suitable for glucose biosensors based on GOx.
