AB  - In this work, a sensitive and selective electrochemical sensor based on 
      polydopamine-reduced graphene oxide (PDA-rGO) and molecular imprinted polymers 
      (MIP) modified glassy carbon electrode for detection of 2,4-DCP was fabricated. 
      The PDA-rGO was obtained through the auto polymerization of dopamine in graphene 
      oxide solution at an alkaline environment. The MIP film was performed on the 
      surface of the PDA-rGO modified electrode by electropolymerization the monomer of 
      o-phenylenediamine (o-PD) with the template of 2,4-dichlorophenol (2,4-DCP). The 
      bare hydroxyl and benzene rings of PDA-rGO could attract positive charged o-PD 
      and provide pi-pi stacking effect with o-PD and 2,4-dichlorophenol, which made the 
      compact imprinted film and more imprinted sites. The Electrochemical impedance 
      spectroscopy (EIS) and cyclic voltammetry (CV) were used to character the MIP and 
      NIP modified electrode in the presence of [Fe(CN)(6)](3-)/[Fe(CN)(6)](4-) as a 
      probe for signal transduction. The relative current intensity of 
      ferro/ferricyanide decreased linearly with increasing concentration of 2,4-DCP 
      with a detection limit of 0.8 nM (S/N = 3). The MIP sensor had a much higher 
      affinity towards 2,4-DCP than other analogues. The proposed method was 
      successfully applied for the determination of 2,4-DCP in real water samples.
