“…Electrochemical methods have been widely applied for the determination of target analytes because they are rapid, sensitive, simple and provide information about the reaction mechanisms [27]. So far, different chemically modified electrodes have been reported for the individual electrochemical determination of GA [1,3,4,27] and FA [17,19,20,26] with high sensitivity and selectivity. However, most of these methods have some drawbacks such as, sophisticated electrode modification procedures and high cost modifiers.…”
