AgNPs were biosynthesized by using an aqueous plant extract of <i>Camellia sinensis</i> (black tea) in which the metabolites worked as reducing and stabilizing agents. The AgNPs and CB nanoparticles were incorporated within a crosslinked chitosan (Ch) film over the surface of a glassy carbon electrode (GCE). The nanomaterials were characterized by scanning electron microscopy (SEM), ultraviolet–visible molecular absorption spectrophotometry (UV–Vis), dynamic light scattering (DLS), zeta potential, and cyclic voltammetry (CV). The sensor modified with both nanomaterials (AgNPs-CB-Ch/GCE) showed a significatively enhanced analytical signal for the ciprofloxacin irreversible oxidation peak. Using square-wave voltammetry (SWV) under the optimized working conditions and the proposed AgNPs-CB-Ch/GCE sensor, the analytical curve displayed two linear concentration ranges of 3.1 to 24.8 µmol L<sup>−1</sup> and of 36.9 to 130.3 µmol L<sup>−1</sup>, with a limit of detection of 0.48 µmol L<sup>−1</sup>. The proposed electrochemical sensor presented good precision as shown from repeatability tests, as well as it was successfully applied in the quantification of ciprofloxacin in the synthetic urine sample, with recovery results close to 100% for both linear concentration ranges.

This declaration propelled the drug hydroxychloroquine into the global spotlight, as it was identified as a potential early treatment for the disease. Consequently, there was a surge in its consumption worldwide, particularly in Brazil. This increased usage has raised concerns about the potential contamination of natural water sources. In response to this concern, the present study proposes an electroanalytical method for detecting hydroxychloroquine in pharmaceutical and drinking water samples. The method aims to study the effects of modifying the sensor with carbon black Super P for HCQ detection, as well as improving the reproducibility and repeatability of the SPCB/GCE. The detection method and sensor modification have been thoroughly optimized for hydroxychloroquine detection.

However, current state-of-art battery technologies are still far away from the requirements.

Therefore, the determination of endosulfan in food samples by a fast, simple, and cost-effective method is pivotal. In this study, an electrochemical sensor based on a polyaniline/Fe-ZnO-modified glassy carbon electrode (PANI/Fe-ZnO/GCE) was developed for the determination of endosulfan in vegetables.

Optical goniometry, even if computer assisted, suffers when the contact angle is 10° or less. In this work, an alternative method of measurement is considered: electrochemical techniques (voltammetry and chronoamperometry), which rely on the transport of material from within the droplet to the conductive surface. As a result of the reactions that take place at the triple phase boundary, these are demonstrated to provide information on the size and the shape of the droplet, including its contact angle, for the cases when the droplets have a redox analyte and either have a supporting electrolyte, or not. The voltammetric behaviour is seen to change from exhaustive, thin film characteristics, to quasi-steady-state signals as the droplet becomes bigger, or the scan rate becomes larger, or diffusion of the redox material inside the droplet becomes slower. One of the surprising outcomes is that there is a zone of planar diffusion only in the case of the supported droplets, with both the droplet size and its contact angle determining whether this is seen at conventional combinations of scan rates and diffusion coefficients. Experimental data are provided which emphasize key features pertaining to the nature of the redox system and illustrate the facile nature of the contact angle estimation process, albeit to within 10% uncertainty.</p>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"27 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141946680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
