PG - 3291-3297 LID - 10.1039/d2an00351a [doi] AB - 3,4-Methylenedioxyamphetamine (MDA) and 3,4-methylenedioxymethamphetamine (MDMA) are the main components of illicit stimulant drugs, also known as "ecstasy", which belong to psychoactive medicine and tend to be increasingly abused among drug addicts worldwide. Herein, an electrochemical sensor based on molecularly imprinted polydopamine (MIP@PDA) was developed to detect MDA and MDMA using differential pulse voltammetry (DPV). An MIP film on a Au electrode was synthesized via electrochemical polymerization with the safe chemical DA as the polymerization monomer and the uncontrolled pharmaceutical intermediate 3,4-methylenedioxyphenethylamine (MDPEA) as the template molecule, which can provide a great quantity of specific binding sites and expand the practical application of the sensor. Due to the superior affinity of MIP@PDA to the target, the proposed sensor displayed excellent analytical performance, with LODs of 37 nM and 54 nM for the determination of MDA and MDMA, respectively. Additionally, this sensor presented suitable selectivity, stability, reproducibility and detection ability in practical urine samples, which suggested that it is a promising candidate as a rapid diagnostic method in drug investigations.
