“…By using graphene and its compounds to modify the electrode, considerable sensitivity and detection limits have been obtained. When graphene and its derivatives are matched with other different materials, different substances can be detected, such as copper, lead, chromium, nickel, and other pollutants [10,11], chlorophenols that are toxic to aquatic organisms [12], melatonin and pyridoxine in plants [13], ascorbic acid, dopamine, and uric acid [14].…”
