Using an aqueous extract of the marine red seaweed Jania rubens, we created a unique biosynthetic technique in this study to manufacture ZnNPs. The produced ZnNPs have a characteristic flower-like form, as seen by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The effective production of ZnNPs and the involvement of biomolecules in the synthesis process were validated by energy-dispersive X-ray spectroscopy (EDAX) and Fourier transform infrared spectroscopy (FTIR) techniques. Using the MTT assay, the cytotoxic effects of the biosynthesized ZnNPs were evaluated, indicating their ability to inhibit MCF-7 breast cancer cells. Furthermore, ZnNPs' cytotoxicity against MCF-7 cells was validated by live/dead imaging experiments, which supported the MTT results.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"39 11","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142548611","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}

Owing to the severe overlap between TOL absorption and Ce–NCDs excitation spectra around 320 nm, TOL could attenuate the emission of Ce–NCDs at 407 nm through primary inner filter effect (IFE).

The suggested approach involved the creation of titanium dioxide (TiO2) nanoparticles through Orthosiphon stamineus extracts of leaves. The synthesized nanoparticles (NPs) were then characterized using XRD, FT-IR, FE-SEM with EDX, and UV–visible spectroscopy. UV–visible spectroscopy validated the presence of optical imperfections in the TiO2 NPs at frequencies of 286 nm. This research specifically focused on examining the photodecomposition and germicidal traits of NPs. Initiatives aimed must be made to mitigate the hazardous effects of TiO2 NPs in an ecologically sensitive way throughout their production. Exposing the dye methylene blue (MB), a major water polluting produced by garment manufacturing, to TiO2 NPs resulted in a considerable increase in photodecomposition efficiency. The photodecomposition process exhibited a rate of breakdown of 83%. The findings indicate that the diameter inhibition zone exhibits the most potent resistance versus pathogenic microorganisms.
