A new electrochemical screening method using a multi-wall carbon nanotube screen-printed electrode combined with square wave voltammetry can detect LSD in forensic samples quickly and reliably. The method shows high stability, with less than 5% variation in measurements, a linear detection range from 0.16 to 40.0 μmol L-1, and a low detection limit of 0.05 μmol L-1. Tests with twenty-three other substances, including phenethylamines and other illicit drugs, demonstrate strong selectivity for LSD. This approach provides a sensitive, reproducible, and straightforward tool for preliminary identification of LSD in seized samples.
