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

“…Previous electrochemical analysis of urine has shown an anodic peak at ∼1.0 V vs. Ag/AgCl. 30,34 However, this was not observed, but would not interfere with the LV peak of interest at 0.6 V vs. Ag. Other potential interferences that are commonly found in urine, including ascorbic acid, are unlikely to inter with the proposed SWV approach as their oxidation occurs at higher potential that the LV peak of interest.…”

“…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.…”
