Abstract: In this paper, a novel sensitive and selective molecularly imprinted electrochemical sensor was presented for the determination of carbaryl (1-naphthyl methylcarbamate). The sensor was constructed by coating a glassy carbon electrode (GCE) with chitosan-AuPt alloy nanoparticles (CS-AuPtNPs), graphene-ionic liquid-nano Au (GR-IL-Au), and followed by electrodepositing carbaryl imprinted poly(p-aminothiophenol) (p-ATP) film. The CS-AuPtNPs and GR-IL-Au composites played the roles to immobilize monomer p-ATP and to improve the electrochemical response; [Fe(CN)6]3-/[Fe(CN)6]4- acted as electrochemical probe. The mechanism of the fabrication process and several important parameters controlling the preparation and electrochemical response of sensor were discussed and optimized. Under the optimal conditions, a linear range from 0.030 μM to 6.0 μM for the detection of carbaryl was obtained. The sensitivity was 4.0 μA/μM mm2 and the detection limit was 8.0 nM (S/N=3). The resulting sensor displayed good selectivity and stability towards carbaryl. It was successfully applied to the determination of carbaryl in practical samples and the recovery was 96 - 105%
