AB  - In the present study we have developed a direct competitive CdSe/ZnS quantum dot 
      (QD) fluorescence assay based on micro-array-imprinted membranes for the 
      determination of triazophos in cabbage and apple. The imprinted membranes were 
      directly synthesized on the surface of a 96-well plate by thermal polymerization 
      using triadimefon as the dummy template. Under optimal conditions, the assay 
      showed an excellent linear response over the concentration ranges of 0.1-10,000 
      mug L(-1) with a good coefficient of determination (R (2)= 0.982). The sensitivity 
      (IC(50)) and limit of detection (LOD, expressed as IC(15)) of the developed assay 
      were 3.63 mg L(-1) and 0.31 mug L(-1), respectively. The applicability of the 
      developed approach was tested for detecting triazophos in incurred samples. The 
      method showed excellent recoveries (109.6-118.9%) and relative standard 
      deviations (RSDs) between 9.9 and 19.5%. The obtained results correlated well 
      with those obtained by LC-MS/MS (R (2)= 0.9995). The competitive assay using 
      CdSe/ZnS QDs as fluorescence-labeled probe showed good sensitivity, steady and 
      fast response, and excellent anti-interference ability compared to conventional 
      fluorescence-quenching methods. Finally, the feasibility of the proposed 
      methodology was successfully applied for detection of triazophos in real samples.
