Selective Recognition of Synthetic Stimulants via a Thio-phene-Derived Polymeric Layer on Graphite Electrodes

“…Several electrochemical strategies have been reported in the literature for the modification of the electrode surfaces for the detection of cocaine, which is one of the most widely used drugs worldwide. The potential use of Schiff base complexes that form stable films on the electrode surface in voltammetric analysis of cocaine was evident from the investigations cited in references [21][22][23].
