AB  - In this work an electrochemical label free DNA biosensor (ds-DNA) for the 
      determination of menadione (MD) was developed. The biosensor was constructed 
      using a modified nanocomposite consisting of Fe(3)O(4) nanoparticles decorated 
      reduced graphene oxide (Gr) on a carbon paste electrode (CPE). Scanning electron 
      microscope (SEM), energy dispersive X-ray (EDAX) and Fourier transform infrared 
      (FT-IR) spectroscopy confirmed the structure of the synthesized nanocomposites 
      (electrode composition). The Gr-Fe(3)O(4) nanocomposites formed a sensitive layer 
      with large surface area. Electrochemical studies revealed that modification of 
      the electrode surface with ds-DNA and Gr- Fe(3)O(4) nanocomposite significantly 
      increases the oxidation peak currents and reduces the peak potentials of MD. 
      Under the optimum conditions, calibration curve was linear in the range of 
      0.3-100.0 nM with a detection limit of 0.13 nM. The relative standard deviation 
      for 50.0 nM was 3.90% (n = 5). The proposed biosensor was successfully applied to 
      the determination of MD.
