The proposed approach measured the quenching effect of CFP on the fluorescence intensity of NFX in acetate buffer solution. The obtained results show that CFP strongly quenches the fluorescence of NFX in a static mechanism. Under the optimal conditions, plotting the fluorescence quenching values (∆F) against CFP concentrations resulted in two ranges varying from 0.8 to 28 μg/mL (r2 = 0.9979) and from 40 to 92 μg/mL (r2 = 0.9929). Furthermore, the limits of quantification and detection were 2.0526 and 0.6773 μg/mL, respectively. In terms of intra- and inter-day recorded precisions (n = 5), the % RSD ranged between 0.31% and 0.6% and 0.55% and 1.02%, respectively. Additionally, practicality/applicability and the green feature of the new method were considered by BAGI and AGREE automated approaches. The new spectrofluorometric approach was positively applied for the quantification of CFP in injection powder and spiked biological fluids, including spiked human urine and plasma samples. According to previously published fluorescence methods, the present method is considered the first fluorescence one for the assay of CFP in human biological fluids with accurate and precise results.","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 1","pages":"e70085"},"PeriodicalIF":3.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015236","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}

Hence, there is an immediate need for replacing carbon-intensive materials with biomaterials. In this respect, this article presents a road-map for moving from polymeric to sustainable waveguides in optical devices. 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. It is important to consider the key points discussed here while making a transition towards sustainable waveguides.","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 1","pages":"e70093"},"PeriodicalIF":3.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143025231","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}
