In this report, the voltammetric detection of aspirin (ASA) was performed using an electrochemical sensor modified with a graphene Nafion nanocomposite film. A Nafion graphene oxide-decorated glassy carbon electrode (GCE) was prepared using a facile drop-casting strategy followed by the reduction of graphene oxide on the surface of the GCE via an electrochemical technique. The electrochemically reduced graphene oxide (ER-GO)/Nafion screen-printed electrode (SPE) was finally fabricated and used for the detection of ASA.
