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).

“…In recent years, numerous methods for detecting SO 3 2− have been reported, including titration, chromatography, capillary electrophoresis, electrochemistry, fluorimetry, and chemiluminescence. [7][8][9][10][11][12] And more and more researchers pay considerable attention to fluorimetry for its high sensitivity and selectivity, simple operation, non-invasiveness, real-time detection, and the desired spatiotemporal resolution. [13][14][15] In a word, fluorescent probes are being used as an effective molecular tool for the determination of various targets.…”

Sulfite (SO3 2−), as an SO2 derivative and important reactive sulfur, plays a vital role in the food industry and various physiological processes. So, it is urgent to seek out an effective method for SO3 2− detection. This work, inspired by the increase of electron-donating groups or electron-withdrawing groups in the molecular structure has a significant effect on the shift of fluorescence emission spectrum, and the nucleophilic addition reaction of SO3 2− to C=C double bond can make a noticeable change in fluorescence spectra. Two cyanine-based fluorescent probes BBHy and NBHy were reasonably designed and synthesized. Among them, near-infrared emitting NBHy with large Stokes shift (277 nm) and fluorescence intensity change in the presence of SO3 2− was selected, and then NBHy displayed superior recoveries for SO3 2− detection in food samples. Besides, NBHy was also successfully applied for SO3 2− sensing in living cells through dual-channel fluorescence imaging, which confidently confirmed the feasibility of our probe design.

Advancement and Perspectives of Sulfite-Based Chemiluminescence, Its Mechanism, and Sensing

This review sums up in detail the sulfite-based chemiluminescence (CL) systems and the impact of various enhancers such as metal ions and their complexes, solvents, nanomaterials (NMs), and carbon dots (CDs) on the CL system. Recent developments and strategies employed to enhance the sulfite-based CL systems are under lengthy discussion, especially in view of the emitting species and the reaction mechanism. The production of free radicals in the systems is thought to be critical for the improvement of the sulfite CL system due to their potential to degrade organic pollutants via advanced oxidation processes (AOPs). However, different chemicals can either favor or disfavor the formation of free radicals, ultimately having a positive or negative impact on CL response. Interestingly, these reagents can be easily differentiated by observing fluctuations in CL response with changes in concentration. We anticipate that an in-depth understanding of the mechanism of action of the sulfite CL system and the role of various enhancers on the efficiency of the system will be helpful in designing a highly selective and sensitive CL system for the detection of specific reagents. The development of improved sulfite CL systems, which use reagents that give a linear CL response with concentration, and their use in chemical, food and agricultural, forensic, pharmaceutical, clinical, agricultural, and environmental analysis is judiciously highlighted.
