| Popis: | This work is concerned with the electrochemical detection of new psychoactive substances (NPSs), in particular 2,5-dimethoxy-N-(2-methoxybenzyl) phenethylamine structures (NBOMes) and the analogous 2,5-dimethoxy phenethylamine structures (2C-X group) on boron-doped diamond (BDD) electrodes. Fast square-wave voltammetry was used to identify the substances in question. The antifouling properties of the BDD surface resulted in stable, repeatable, sensitive and unique voltammetric responses for these NPSs, producing different voltammetric signatures. Different NBOMes were identified by voltammetric methods in blotting paper seized from the drug market, without any interference from LSD, another psychedelic drug distributed via blotting paper. The proposed method achieved detection limits lower than 0.1μmolL−1 with high precision (RSD |
