摘要

本文报道了一种基于电化学合成的聚(对氨基苯磺酸)/还原氧化石墨烯(聚(p-ABSA)/RGO)复合修饰玻碳电极的新型、灵敏的吗啡传感器。用FT-IR、FESEM、EDX等技术对所制备的复合材料进行了系统表征。采用循环伏安法和差分脉冲伏安法研究了吗啡在pH 7.0的生理磷酸盐缓冲液上的电化学反应。该传感器的线性响应范围为50 nM-80µM, MO的检测限为47 nM。此外,该传感器还具有良好的稳定性、可重复性和抗干扰性。

A novel voltammetric sensor for morphine detection based on electrochemically synthesized poly (p-aminobenzenesulfonicacid)/reduced graphene oxide composite
In this work a novel and sensitive sensor for morphine (MO) based on electrochemically synthesized poly(p-aminobenzenesulfonicacid)/reduced grapheneoxide (poly(p-ABSA)/RGO) composite modified glassy carbon electrode was reported. The prepared composite was systematically characterized by various techniques like FT-IR, FESEM and EDX. The electrochemical response of morphine on this sensor was investigated in physiological pH 7.0 phosphate buffer solution by cyclic voltammetry and differential pulse voltammetry. The fabricated sensor provides a linear response in the range of 50 nM-80 µM with a detection limit of 47 nM for MO. In addition the sensor also provides good stability, repeatability and anti interference property.
