Design of CdV₂O₄-V₆O₁₃ micro flowers for non-enzymatic electrochemical detection of urea

Detection of urea is generally accomplished by urea biosensors, which necessitates the immobilization of enzymes (i.e. urease), hence limiting their utility. In this report, we have demonstrated the non-enzymatic electrochemical detection of urea by means of CdV₂O₄-V₆O₁₃ micro-flowers (CdV₂O₄-V₆O₁₃ MFs). The physicochemical properties of this material were revealed by different characterization methods, which include the powder X-ray diffraction (PXRD) technique, field-emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX) and Fourier transform infrared (FT-IR) spectroscopy. Finally this material was successfully employed for the non-enzymatic detection of urea by electrochemical method. This detection ability can be accredited to the high sensitivity, large electroactive surface area and unique morphology of CdV₂O₄-V₆O₁₃ MFs.
