Zinc oxide nanoparticles (NPs) currently grabbed attention of multiple medical fields owing to their unique ability to safeguard against cellular damage and alleviate serious human diseases via processes related to metabolism. This work focused on the generation of ZnO NPs using the peel of <i>Cucumis melo</i> fruit. The NPs were then analyzed and characterized using UV–Vis spectroscopy. The results indicated that at a wavelength of 352 nm, it was proven that the biosynthesis of ZnO NPs had occurred. The XRD pattern indicated the presence of dense crystal structures. The field emission scanning electron microscope (FE-SEM) picture confirmed the existence of polygonal-shaped ZnO NPs. The findings indicate that the produced ZnO NPs possess tough antibacterial properties against Gram-positive and Gram-negative microorganisms. When the ZnO NPs were exposed to direct sunshine for 80 min, they showed an 89% dye breakdown efficiency. This research specifically focused on the decomposition of reactivity dyes, with methylene blue dye being used as the target dye. The work demonstrates that the biosynthesis of ZnO NPs has a crucial and versatile role in the biological and environmental sectors.</p>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"39 10","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142451727","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}

To address this issue, <i>rbio 2.4</i> wavelet transformation was employed to obtain zero-crossing points in the synchronous fluorescence spectra of losartan and rosuvastatin at 346 and 408 nm, respectively, making their quantification possible. The developed method was validated according to the ICH guidelines and displayed high accuracy, precision, and specificity. The method exhibited excellent linearity over concentration ranges 0.2–2.0 and 0.25–2.0 μg/mL for losartan and rosuvastatin, respectively. In addition, LOD and LOQ were 0.046 and 0.140 μg/mL for losartan and 0.036 and 0.110 μg/mL for rosuvastatin, respectively, indicating the high sensitivity of the developed method. Moreover, greenness and blueness assessments were carried, revealing a high AGREE score of 0.71 and BAGI score of 77.5 for the developed method, making it a promising greener alternative for the reported chromatographic methods.
