Diazinon or O,O-diethyl-O-(2-isopropyl-4-methyl-6-pyrimidinyl)-O,O-diethyl-O-(2- isopropyl-4-methyl-6-pyrimidinyl)- phosphorothioate, was first registered as an insecticide in the U.S. However, it was categorized in the limited group of pesticides due to high toxicity for birds, aquatic animals, and humans. Like other organophosphorus pesticides, this compound exhibits inhibitory effects on acetylcholinesterase enzyme. The inhibition of the enzyme leads to the accumulation of acetylcholine and causes the death of insects. DZN is considered a toxic compound for humans due to its high adsorption via skin and inhalation, which leads to the emergence of different symptoms of toxicity. When DZN is used for plants, the compound residues in crops enter the food chain, and hence, bring about different problems for human health. Moreover, the compound is easily washed by surface water and enters the groundwater. Its entrance into aquatic environments can negatively affect a wide range of non-targeted organisms. Thus, researchers are seeking to find fast and precise methods for the recognition of DZN. The electrochemical method for recognizing the compound in real samples is preferable to other analytical methods. Because this method can be used without spending time preparing the sample, it is simple, fast, and cost-effective. The present study is an overall review describing electrochemical-based methods for the recognition of DZN. Methods of modifying electrodes with CNT, polymers, biomolecules, and the simultaneous use of multiple methods are evaluated and compared. The influential factors contributing to the improvement of the signal response are also explained.

“…The cyclic voltammetry (CV), square wave voltammetry (SWV) and spectroelectrochemical measurements were carried out with a Gamry Reference 600 potentiostat/ galvanostat utilizing a three-electrode configuration at 25 C by following the procedure conducted in our previous papers. [61,62] Glassy carbon electrode (GCE), Pt wire and Ag/AgCl electrode served as the working, counter and reference electrodes, respectively. TBAP dissolved in DMSO was employed as the supporting electrolyte at a concentration of 0.10 M. UV-Vis absorption spectra were measured using Ocean Optics QE65000 diode array spectrophotometer.…”

Interest in Cd complexes has been growing in recent years. Cd complexes are considered a potential solution in the search for novel antibiotics that can fight antimicrobial resistance. In addition, Cd complexes draw attention to material chemistry. The main objective of this work was to prepare the first Cd(II) complexes with anionic forms of pyridine‐based thiazolyl hydrazone (THs) ligands HLS2 [(E)‐4‐(4‐methoxyphenyl)‐2‐(2‐[pyridine‐2‐ylmethylene]hydrazinyl)thiazole] and HLS3 [(E)‐2‐(2‐[pyridine‐2‐ylmethylene]hydrazinyl)‐4‐(p‐tolyl)thiazole] and perform their structural and spectroscopic characterization, as well as stability in solution and upon heating. Studies related to their biological activities and possible electrochromic applications are also being conducted. Complexes [Cd(HLS2)2] (1) and [Cd(HLS3)2] (2) have been characterized by a single‐crystal X‐ray diffraction and computational analysis of intermolecular interactions responsible for their solid‐state structures was performed. Thermal stability of 1 and 2 in the solid‐state was analyzed by TGA/MS, where as their solution stability was determined by the spectrophotometric titration method. Electrochemical and in situ UV–Vis spectroelectrochemical analyses of 1 and 2 were carried out to determine redox mechanisms and the influence of the substituents and electrolytes on their redox responses. The antioxidant capacity of both complexes was tested in antioxidant assays, while their antimicrobial activity was tested against five Gram‐positive and four Gram‐negative bacteria, as well as against three fungi. The obtained results indicate their potent antioxidant capacity. The antimicrobial activity of investigated compounds on almost all tested bacterial strains was stronger than that of the standard antibiotic erythromycin. The results of docking studies indicate that the minor groove DNA is the possible biological target of 1 and 2.

Various carbon-based sensors (graphene, carbon nanotubes, graphite, pencil graphite, glassy carbon, etc.) have distinctive behavior and a broad range of importance for identifying sex hormones like estriol, estradiol, estrone, progesterone, and testosterone. The current review emphasizes voltammetric, amperometric, and electrochemical impedance spectroscopic methods for detecting some of these hormones. The existence, structural aspects, nature, and biological importance of each hormone were analyzed in detail and their analysis with different electroanalytical methods was considered. Unique methodologies and innovations of electrochemical sensors for hormones based on carbon materials modified by different agents were examined. In this review, the interaction among various sensor materials and analytes in different supporting electrolyte media is premeditated. The most important significances of the electroanalytical methodologies were discussed based on sensor selectivity, sensitivity, stability, the limit of detection, repeatability, and reproducibility.
