Abstract: A novel electrochemical sensor was prepared by graphene-chitosan molecularly imprinted film, which casted on the gassy carbon electrode by electrodeposition, using L-tryptophan (L-Trp) as the template. The prepared film was investigated by scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The enantioselective performance and the optimal conditions for L-Trp detection were evaluated by electrochemical technique in detail. Under the optimum conditions of 1 mg mL-1 graphene doping concentration, 300 s electrodepositing time, the prepared sensor showed a excellent chiral recognition to Trp in pH =6 NaCl solution and linearly selective detection of L-Trp in the range of 0.17 ~ 25 μmol L-1 was found, with a limit of detection of 0.04 μmol L-1 (S/N =3).
