Abstract

A graphene nanosheets (GNS) based nanosensor to study the electrochemical response characteristics of pralidoxime has been developed. The fabricated nanosensor was characterized by scanning electron microscopy, electrochemical impedance spectroscopy, square wave voltammetry and cyclic voltammetry. The proposed electrochemical sensor exhibited good analytical performance including high sensitivity and selectivity as compared to bare glassy carbon electrode (GCE). Different electrochemical parameters such as charge transfer resistance (Rct), surface area (A) were also calculated. The sensor shows an excellent performance for pralidoxime sensing with good reproducibility and stability of the developed method. The fabricated GNS/GCE sensor shows great promise for simple, sensitive, quantitative screening of pralidoxime using voltammetric techniques.
