An electrochemical assay for diazinon pesticides was developed using cyclic voltammetry and square-wave anodic and cathodic stripping voltammetry. The method has a linear working range from 6 to 62 ng L-1. The detection limit is 0.5 ng L-1 (1.64 pM), and the relative standard deviation at a diazinon concentration of 6.0 mg L-1 was 0.06% (n=15) in an 0.1 M ammonium phosphate electrolyte solution. The results of the application of the sensor were compared with those of other common spectrometric and electrochemical methods. The method was also applied to cucumber juice and the deep brain cells of a live carp in real conditions.
