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- 80μM with a detection limit of 47 nM for MO. In addition the sensor also provides good stability, repeatability and anti interference property. [ABSTRACT FROM AUTHOR] |
