“…Less complicated electrochemical methods are gaining favor over more traditional techniques because of their simplicity, rapidity, sensitivity and selectivity. 8 In general, the performances of electrochemical sensors depend on electrode modification, which can involve various materials. Significant improvements in performances have been achieved by using modifying electrodes with carbon nanomaterials, which exhibit high stability, large surface areas, excellent conductivity and good catalytic properties.…”
