However, citric acid-capped GNPs are not optimized for constructing aptasensors. In this study, we aimed to develop a more sensitive, selective, and efficient antioxidant-capped GNP (A-GNP) probe for the colorimetric detection of kanamycin. We assessed the performance of A-GNPs synthesized with polyphenols, multi-carboxylic acids, ascorbic acid, and kojic acid, as both reducing agents and stabilizers. Among the tested antioxidants, only ascorbic acid and gallic acid mediated the formation of A-GNPs at room temperature and these could be optimized to construct aptasensors by functionalizing the A-GNPs with poly(adenine)-tailed DNA aptamers (pA-apt). The colorimetric probe using gallic acid-capped GNPs had a limit of detection for kanamycin of 6.2 nM, which is lower than the 22.0 nM value obtained using citric acid-capped GNPs. Furthermore, this aptasensor showed high selectivity for kanamycin, indicating that the A-GNP/pA-apt probe could be applied as a novel aptasensor for antibiotic detection in real-world contexts.</p></div>","PeriodicalId":684,"journal":{"name":"Korean Journal of Chemical Engineering","volume":"42 5","pages":"1099 - 1107"},"PeriodicalIF":2.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among soft electronic materials, poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) hydrogels are distinguished by their combined ionic–electronic conductivity, tissue-like mechanics, and biocompatibility. Despite these advantages, PEDOT:PSS hydrogels still face challenges, including high water content, mechanical weakness, and limited adhesion to conventional electronic materials. These challenges are further intensified by the incompatibility of PEDOT:PSS with high-temperature processing and chemically demanding fabrication techniques. Consequently, research has increasingly focused on developing PEDOT:PSS hydrogels with advanced fabrication methods that enable scalable production, complex structure, and high resolution to meet the requirements of soft electronics. This review explores the integration of PEDOT:PSS hydrogels with soft electronics from hydrogel-to-device and device-to-hydrogel perspectives. It explores strategies to enhance the performance of PEDOT:PSS hydrogels and address fabrication challenges. Both top-down (e.g., scalable fabrication and high precision) and bottom-up (e.g., tunable conductivity and multifunctionality) approaches are examined, emphasizing advances that improve hydrogel integration with manufacturing technologies.

The synthesized Schiff bases were completely characterized by IR, NMR and LC–MS. Moreover, both synthesized compounds were evaluated against acetylcholinesterase and butyrylcholinesterase as two important targets in the treatment of Alzheimer’s disease. Approximately, both new compounds were more potent than positive control tacrine against these studied enzymes. Cholinesterase enzyme inhibition is a widely used treatment approach for a variety of mental illnesses. Through the inhibition of the acetylcholinesterase enzyme, which hydrolyzes acetylcholine, cholinesterase inhibitors directly improve cholinergic transmission. Using the SAR (structure–activity relationship) approach to connect different functional groups, the influence of this synthesized molecule on the activity was examined. The investigated compounds were then structurally characterized at the levels of B3LYP, HF, and M062X/6–31+G(d,p). Using maps of molecular electrostatic potential (MEP), the active sites of the compounds under study were identified. In the end, our focus was on evaluating the drug’s potential as an inhibitor against the Alzheimer’s disease, specifically targeting the Alzheimer’s disease protein, that are Acetylcholinesterase (AChE) (PDB ID: 1OCE, 1QTI, and 4M0E) and Butyrylcholinesterase (BChE) (PDB ID: 6R6V and 2WSL).

In this work, copper oxide (CuO) catalysts were synthesized using mesoporous silica (SiO₂) as a template for the activation of peroxomonosulfate (PMS) for the removal of the target pollutant bisphenol A (BPA). The results showed that the CuO catalysts not only increased the specific surface area and active sites, but also enhanced the efficient activation of PMS to produce a large amount of reactive oxygen species. In this paper, the degradation process and mechanism of BPA by CuO in PMS activation system were comparatively investigated by characterization data and experimental data. Under the optimum conditions, the degradation rate of BPA (30 mg/L) was as high as 97.8%, which was basically completely degraded. The CuO/PMS catalytic system involves both radical and non-radical pathways, with the non-radical ¹O₂ being the main reactive oxygen species for the degradation of BPA. The reaction intermediates were identified by liquid chromatography–mass spectrometry (LC–MS), and the degradation mechanism and the degradation pathway of the catalyst were proposed. It was shown by cycling experiments that the degradation rate of BPA in the system reached more than 65% at 60 min when the catalyst CuO was reused for the fifth time.
