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...

An innovative approach for selective and robust screening of NBOHs, NBOMes, and LSD in forensic samples using a 3D-Printed electrochemical double cell.

Talanta August 15, 2024 Larissa M.a. Melo, Lucas V de Faria, Luciano C Arantes et al. 8 citations

Lysergic acid diethylamide (LSD) and two phenethylamine classes (NBOHs and NBOMes) are the main illicit drugs found in seized blotter papers. The preliminary identification of these substances is of great interest for forensic analysis. In this context, this work constitutes the inaugural demonstration of an efficient methodology for the selective detection of LSD, NBOHs, and NBOMes, utilizing...

Psychedelic 25H-NBOMe attenuates post-sepsis depression in rats.

Neuroscience Letters June 21, 2024 Barbara G Ferri, Cintia O De Novais, Viviana C T Rojas et al. 3 citations

Sepsis-associated encephalopathy, which manifests in severe cognitive and depressive symptoms, is directly linked to neuroinflammation. Our study investigates the efficacy of 25H-NBOMe, a phenethylamine, in alleviating these symptoms, potentially offering an innovative treatment for post-sepsis depression. Wistar rats, weighing between 250-300 g, were subjected to cecal ligation and puncture...

Exposure to the Psychedelic Substance 25H-NBOMe Disrupts Maternal Care in Lactating Rats and Subsequently Impairs the Social Play Behavior of the Offspring.

Behavioural Brain Research February 1, 2024 Larissa M.a. Melo, Wellington A De Barros, Ângelo de Fátima et al.

Given the critical role of maternal care in the neurodevelopment of offspring, this study aimed to investigate the effects of the psychedelic substance 25H-NBOMe on maternal behavior in lactating rats and its subsequent impact on the social and neurodevelopmental behavior of the offspring. We administered two different dosages of 25H-NBOMe (0.3mg/kg and 1.0mg/kg; i,p,) to lactating rats and...

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...

Psychoactive substances 25H-NBOMe and 25H-NBOH induce antidepressant-like behavior in male rats.

European Journal of Pharmacology September 15, 2023 Barbara G Ferri, Cintia O De Novais, Raquel S Bonani et al. 11 citations

Ring-substituted phenethylamines are believed to induce psychedelic effects primarily by interacting with 5-hydroxytryptamine 2 (5-HT2A) receptors in the brain. We assessed the effect of the psychedelic substances 25H-NBOMe and 25H-NBOH on the depressive-like behavior of male adult rats. Naive Wistar rats were divided into groups to assess the effects of different doses (0.1 mg/kg, 1 mg/kg, and...
