Electrochemical sensing of ecstasy with electropolymerized molecularly imprinted poly(o-phenylenediamine) polymer on the surface of disposable screen-printed carbon electrodes

•Electroanalysis of ecstasy (MDMA) using screen-printed carbon electrodes (SPCEs).•Molecularly imprinted polymers (MIPs) were developed for MDMA.•The polymerization of o-phenylenediamine (o-PD) and its interaction with MDMA was simulated by DFT methods.•The SPCE-MIP selectively analysed MDMA by square-wave voltammetry (SWV).•First time a SPCE-MIP sensor was developed for MDMA.
