In order to overcome toxic side effects and enhanced bioavailability of 7AAMD, micellar drug carrier systems could be useful. We have used cationic (hexadecetyltrimethylammonium bromide [CTAB]), anionic (sodium dodecyl sulphate [SDS]) and non-ionic (<i>t-</i>octylphenoxypolyoxyethanol, Triton-X100 [TX 100]) surfactants to prepare micelle. We have explored the mechanism of the interaction of 7AAMD with micelles using steady-state and time-resolved fluorescence spectroscopy. Our results revealed that the Stokes' shift values of 7AAMD were decreased in all three micellar medium compared to that in the absence of any micelle. Thus, 7AAMD is localized in less polar microenvironment of micelles than bulk water. In addition, from the time-resolved fluorescence study of 7AAMD, we found that the relative contribution of the conformers of 7AAMD depended on the surfactant head group. Furthermore, acrylamide induced fluorescence quenching study shows differential accessibility of the quencher molecules towards 7AAMD depending on the ionic nature of the surfactant head group. In the presence of acrylamide, 7AAMD was expelled out from the non-ionic TX 100 micelle but not in CTAB and SDS micelle. Thus, our results are valuable to design new drug delivery system for AMD-like antitumor agents.</p>\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 2","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143068528","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}

Herein, a new spectrofluorometric method was created for the determination of nitrofurantoin in water samples from fish ponds. Carbon quantum dots were functionalized with nitrofurantoin tetra phenyl borate modifying their surface to be selective for nitrofurantoin quantification. When nitrofurantoin is present, the functionalized carbon quantum dots show concentration-dependent fluorescence quenching, allowing estimation of the drug. The method was validated and demonstrated accepted linearity in the range of 5–150 ng/mL, with a limit of detection at 1.251 ng/mL. The method offers a broader and more sensitive detection range compared with a previous UHPLC method.

Previous reports indicate that luminescent fibres exhibit better photon concentrations of nearly 30%–33% higher than flat-plate polymeric waveguides. It is also verified that the photon in-out ratio increases by 3.44 times when the waveguide geometry is changed from planar to an equivalent area of fibre bundle with the same luminophore. Meanwhile, transparent wood (Twood) is gaining attention as a green alternative to acrylic sheets. The structure and function of transparent wood conforms well with the fibre-based waveguides of luminescent solar concentrators (LSCs). Therefore, it is intriguing to compare Twood with intrinsic micro fibrillary interior with fibre-based LSC as a natural alternative. This review provides an in-depth analysis, emphasizing the benefits and associated challenges in using cylindrical concentrators over planar LSCs. The paper collects and compares the phenomenon of light guiding of cylindrical and fibre-based LSCs with that of Twood.
