Overview of cocaine identification by vibrational spectroscopy and chemometrics

Danielle Kochenborger John et al.

Summary: The use of non-destructive forensic methods for cocaine identification is crucial due to the large number of seized samples. Spectroscopic techniques such as ATR-FTIR, Raman, and NIR spectroscopy offer fast and cost-effective analysis, along with the reanalysis of samples. When combined with chemometrics, these methods allow for accurate determination and quantification of cocaine, overcoming the limitations of existing techniques. This review article comprehensively discusses the application of spectroscopic techniques in identifying cocaine in various forms and matrices, including food and textiles used for smuggling. It also explores the chemometric identification of cocaine in oral fluid and water, as well as the use of portable equipment for vibrational spectroscopy. The article aims to evaluate the main chemometric applications of spectroscopic data and provide new perspectives on cocaine identification using chemometrics.

Electrochemistry of the synthetic tryptamine 5-MeO-MiPT at glassy carbon and screen-printed electrodes: A rapid and simple screening method for application in forensic analysis

Larissa M. A. Melo et al.

Summary: This study investigates the electrochemical behavior of 5-MeO-MiPT using carbon electrodes for the first time. It shows that a graphite screen-printed electrode exhibits many electrochemical processes for 5-MeO-MiPT, while a glassy carbon electrode only shows one oxidation process. The proposed method using differential pulse adsorptive stripping voltammetry on the graphite screen-printed electrode shows great potential as a simple, fast, and selective screening method for 5-MeO-MiPT in forensic scenarios.
