AB  - Herein, we report a highly selective dopamine electrochemical sensor based on 
      electrochemically pretreated graphite/nafion composite modified screen printed 
      carbon (SPC) electrode. Electrochemically activated graphite/nafion composite was 
      prepared by using a simple electrochemical method. Scanning electron microscope 
      (SEM) used to characterize the surface morphology of the fabricated composite 
      electrode. The SEM result clearly indicates that the graphitic basal planes were 
      totally disturbed and leads to the formation of graphite nanosheets. The 
      composite modified electrode showed an enhanced electrocatalytic activity toward 
      the oxidation of DA when compared with either electrochemical pretreated graphite 
      or nafion SPC electrodes. The fabricated composite electrode exhibits a good 
      electrocatalytic oxidation toward DA in the linear response range from 0.5 to 70 
      muM with the detection limit of 0.023 muM. The proposed sensor also exhibits very 
      good selectivity and stability, with the appreciable sensitivity. In addition, 
      the proposed sensor showed satisfactory recovery results toward the commercial 
      pharmaceutical DA samples.
