Summary: In 2012, the FDA approved tofacitinib citrate (TOF) for the treatment of rheumatoid arthritis. Electroanalytical methods using glassy carbon electrode (GCE) and boron-doped diamond electrode (BDDE) were developed to determine TOF. The effects of pH, electrolyte, and scanning rate on TOF's peak current and potentials were investigated. The proposed methods showed excellent recovery results for determining TOF in pharmaceutical dosage forms and serum samples.

Summary: Theoretical and electrochemical behavior of the herbicide fluometuron was investigated using a glassy carbon electrode for the first time. The study found that fluometuron exhibited an irreversible profile with a well-defined anodic peak through cyclic voltammetry. The presence of defects on the electrode surface induced the dissociation and adsorption of fluometuron, affecting the electroanalysis. Differential pulse voltammetry was successfully employed for the determination of fluometuron under optimized conditions.

Summary: The electrochemical properties of quetiapine fumarate were studied using a multi-walled carbon nanotube modified electrode. The optimal concentration of multi-walled carbon nanotubes was determined. The oxidation process of quetiapine fumarate was found to be irreversible and controlled by adsorption. The linear ranges and detection limits for differential pulse stripping voltammetry and square-wave stripping voltammetry were determined. The methods were successfully applied for the analysis of quetiapine fumarate tablets. The groups responsible for the oxidation reaction of quetiapine fumarate were investigated using model substances.

Summary: The electrochemical oxidation of 5-methylcytosine was studied at glassy carbon electrode in aqueous solution, revealing a single, irreversible reaction step controlled by diffusion, generating intermediate radicals. C5 methylated pyrimidines are more easily oxidized and reactive compared to unmethylated bases. A new electroanalytical method using differential pulse voltammetry for quantification of DNA methylation was proposed, showing promising results for detection of 5-mCyt.

Summary: The study presented a sensitive detection method for nitroaromatic explosives using a GC/MWCNTs/PEI electrode coated with gold nanoparticles. The method successfully detected TNT, DNT, 2,4-DNP, PA, and tetryl in a linear range, with detection limits ranging from 15 μg L-1 to 135 μg L-1. This method was also validated against the reference LC-MS method for analyzing explosives in soil samples.

Summary: Stencil-printed carbon electrodes (SPCEs) play a crucial role in the development of cost-effective electrochemical sensors, but typically suffer from poor electrochemical properties. This study systematically investigates the impact of different carbon particle types and plasma cleaning on the fabrication and electrochemical properties of SPCEs. The results demonstrate that careful selection of carbon particle type and plasma treatment can significantly improve the electrochemical properties of SPCEs, paving the way for the development of high-performance electrochemical point-of-need sensors.

Summary: In this study, an electrochemically activated glassy carbon electrode (AGCE) was successfully fabricated and applied for the sensitive and selective detection of sunset yellow (SY). The AGCE demonstrated improved performance compared to the non-activated glass carbon electrode (GCE). Under optimal analytical conditions, the proposed sensor showed good linearity and low detection limit for the detection of SY, and was successfully applied for the detection of SY in actual samples.
