Abstract: A novel film of overoxidized polypyrrole and carboxylic multi-walled carbon nanotubes (c-MWNTs) was fabricated with molecular imprinted technique for dopamine by a direct and facile electropolymerization method. The resulting modified electrode surface was characterized with electrochemical impedance spectroscopy and Fourier transform infrared spectroscopy. The results demonstrated that the modified electrode not only possessed a good sensitivity but also exhibited a high selectivity toward DA which making anodic potential difference of DA and AA is 318 mV in DPV. Under the optimum conditions, the linear range of the dopamine biosensor ranges from 5.0 x 10-8 to 6.0 x 10-6 mol/L with a detection limit of 5.0 x 10-9 mol/L
