摘要
A simple and rapid protocol for the synthesis of polystyrene-graphene oxide nanocomposite （PS/GONC） was achieved for first time using an in situ polymerization method. PS/GONC modified glassy carbon electrode （PS/GONC/GCE） has been employed as an efficient nanosensor for the electrooxidation of histamine. The PS/GONC/GCE is used as an electrochemical nanosensors for monitoring histamine using differential pulse voltammetry techniques （detection limit 0.03 μmol/L）. In addition, the prepared nanosensor was successfully applied to determine histamine in fish samples, yielding satisfactory results. The spiked recoveries were in the range of 98.2%-103.1%.
