Zolpidem is an imidazopyridine derivative, non-benzodiazepine and sedative-hypnotic medicine. It is a widely prescribed medication in adults used for the short-term treatment of a sleep problem called insomnia and frequent awakenings. In this work, the zolpidem was determined using Ag/ZnO nanoplates modified glassy carbon electrode (Ag-ZnO/GCE). Electrochemical behavior of the zolpidem was investigated by differential pulse voltammetry (DPV), chronoamperometry (CHA), and cyclic voltammetry (CV) using the Ag-ZnO/GCE. The results revealed that, the current responses of the zolpidem improved significantly due to the high catalytic activity and electron transfer reaction of nanoplates. The linear range of zolpidem was found to be from 0.1 µM to 500.0 µM with the detection limit of 0.03 µM. In addition, this original sensor showed numerous benefits such as reproducibility, high stability, and rapid response (20 s).

A potent selective acrylamide liquid sensor based on the reaction of acrylamide with 2-(5-Bromo-2-pyridylazo)-5-[N-n-Propyl-N-(3-Sulfopropyl) amino] aniline reagent is successfully designed. The characteristics slope (52.33 mV/decade), linearity usable range from 1.0 × 10−7–1.0 × 10−1 molar, limit of detection (1.6 × 10−8) molar, selectivity attitude to several inorganic cations, amino acids and sugars, time of response (8 s), lifetime (four months), pH effect on the electrode potential and the basic validation parameters were studied. The desirable pH applicable range was 3.0–6.5, and the restraint of the developed sensor is independent on this working pH range. The deployed electrode was effectively applied for rapid inexpensive analysis of acrylamide cations in food products with comparison to high-performance liquid chromatographic method and the results were agreeable with each other. The obtained data by the suggested electrode were treated statistically and compared with the various recently published acrylamide sensors.

A novel electrochemical sensor for the selective and sensitive detection of droxidopa in presence of carbidopa at physiological pH was developed by the bulk modification of carbon paste electrode (CPE) with copper oxide (CuO), ionic liquid and Mn (III) salen (CuO-IL-MS/CPE). Large peak separation, good sensitivity and stability allow this modified electrode to analyze droxidopa individually and in the presence of carbidopa. Applying differential pulse voltammetry (DPV), a linear dynamic range of 0.5-600.0 µM with detection limit of 0.2 µM was obtained for droxidopa. Finally, the proposed method was applied to the determination of droxidopa and carbidopa in real samples.
