Colorimetric-Electrochemical Combined Method for the Identification of Drugs of Abuse in Blotter Papers: A Powerful Screening Technique Using Three Analytical Responses.

ACS Omega April 29, 2025 Cláudia Mancilha Rocha, Larissa Magalhães de Almeida Melo, Augusto César Carvalho Santos et al. 5 citations

Lysergic acid diethylamide (LSD) and phenylethylamine derivatives (NBOHs and NBOMes) are commonly found on seized blotter papers, posing public health risks. Efficient screening methods for identifying these substances are currently limited. To address this, a novel protocol combining colorimetric and electrochemical techniques was developed as a screening method for drugs of abuse in blotter...

Environmentally friendly screen-printed electrodes for the selective detection of 4-bromo-2,5-dimethoxyphenethylamine (2C-B) in forensic analysis.

Analytical methods : advancing methods and applications November 14, 2024 Anne Alves Macedo, Dilton Martins Pimentel, Larissa Magalhães de Almeida Melo et al. 6 citations

In response to the growing need for sustainable analytical methods, this study explores the repurposing of screen-printed electrodes (SPEs) that would otherwise be discarded. This involves recoating the working electrode surface with a graphite (Gr) and chitosan (CTS) dispersion, creating a reusable SPE (SPE-Gr/CTS). Demonstrating its utility, SPE-Gr/CTS was employed for the detection of...

Comprehensive detection of lysergic acid diethylamide (LSD) in forensic samples using carbon nanotube screen-printed electrodes.

Analytical methods : advancing methods and applications November 9, 2023 Anne Alves Macedo, Luciano C Arantes, Dilton Martins Pimentel et al. 13 citations

Lysergic acid diethylamide (LSD) is a prevalent psychoactive substance recognized for its hallucinogenic properties, often encountered in blotter papers for illicit consumption. Given that LSD ranks among the most widely abused illicit drugs globally, its prompt identification in seized samples is vital for forensic investigations. This study presents, for the first time, an electrochemical...
