Enhancement of the electrochemical behavior of CuO nanoleaves on MWCNTs/GC composite film modified electrode for determination of norfloxacin

► A novel and single step method for the synthesis of PDDA stabilized CuO nanoleaves. ► The CuO nanoleaves were fabricated on MWCNTs/GC modified electrode for the electrochemical oxidation of norfloxacin. ► The obtained CuO/MWCNTs/GC modified electrode exhibits excellent electrochemical activity for the determination of norfloxacin at low operating potential of +0.91 V.
