Summary: PPy.SDS-coated carbon fiber electrodes demonstrated enhanced drug sensing capabilities compared to bare carbon fibers, with a 14-fold increase in electrochemical surface area. The use of a large counter anion as dopant, such as dodecyl sulfate, resulted in a greater drug sensing response. Differential pulse voltammetry (DPV) with PPy.SDS fiber electrodes was able to detect paracetamol with a detection limit of 34 μM and a linear response range of 50-500 μM, even in the presence of interferents like dopamine and ascorbic acid at 100 μM concentrations. This indicates the potential for real-world applications of PPy.SDS electrodes in drug sensing, with the ability to detect anti-psychotic medication like clozapine at low concentrations.

Summary: The electrochemical behavior of sulfamethoxazole (SMX) was studied on the surface of glassy carbon electrode coated with Nafion, GO, ZnO, GO-ZnO nanocomposites using cyclic voltammetry. The results showed that the GO-ZnO nanocomposite electrode with Nafion coating exhibited a significant increase in background current for SMX detection. The study also investigated the effects of GO, ZnO, and varying amounts of ZnO with Nafion coating on the electrochemical performance of the electrodes. The results showed that the GO-ZnO/GC electrode had reduced peak currents but increased potential voltage difference compared to the GO/GC electrode.
