Can synthetic cannabinoids be reliably screened with electrochemistry? An assessment of the ability to screen for synthetic cannabinoids STS-135 and BB-22 within a single sample matrix

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

“…A previous study using BDDE identified pH 12.0 as optimal for discriminating LSD from 20 possible interferents commonly found in seized blotting paper samples. 16 While BDDE lost sensitivity at this pH, Fig. 3 reveals that SPE-MWCNT maintains good sensitivity for LSD at pH 12.0, with two very well-defined oxidation processes.…”

“…Regarding other approaches for electrochemical detection of other drugs, as demonstrated in the review, 52 or in recents works 16,53 the proposed method evaluates a much greater quantity of interferents than those commonly analyzed with excellent sensitivity. As far as we know, for LSD detection, this is the rst work to address so many possible interferers, providing a method with high selectivity.…”

“…Recent years have witnessed the rise of electrochemical sensors as attractive tools for forensic analysis, serving as screening methods for various drugs 16–19 , including phenethylamines. 20–23 These electroanalytical methods offer numerous advantages, such as low cost, versatility, selectivity, sensitivity, portability, and simplicity.…”

Towards voltammetric point of care detection of leucovorin

“…Again, this could be attributed to the poorer electron transfer kinetics and/or a potential interaction of the LV with the components of the saliva. 30,34 Another possibility is the non-uniform distribution or aggregation of the LV within the artificial saliva. In order to address the issues observed for the SWV response obtained directly from saliva, the matrix was diluted with 0.1 M NaCl.…”

“…SWV, a technique under the umbrella of electrochemical methods, offers distinct advantages such as enhanced sensitivity and specificity, making it an attractive candidate for LV detection. [28][29][30] Furthermore, the utilization of SPCEs adds to this method's appeal, given their versatility, ease of fabrication, and cost-effectiveness.…”
