Pt-Co alloy nanowire array was directly synthesized by electrochemical deposition with polycarbonate template at - 1.0V and subsequent chemical etching of the template. The use of Pt-Co alloy nanowire array-modified electrode (Pt-Co NAE) for the determination of morphine (MO) is described. The morphology of the Pt-Co alloy nanowire array has been investigated by scanning electron microscopy (SEM) and energy disperse X-ray spectroscopy (EDS) analysis), respectively. The resulting Pt-Co NAE offered a linear amperometric response for morphine ranging from 2.35 × 10 -5 to 2.39 × 10 -3 M with a detection limit of 7.83 × 10 - 6 M at optimum conditions. This sensor displayed high sensitivity and long-term stability. |
