The APTA sensor/Cy3 probe consisted of cadmium telluride quantum dots modified with thioglycolic acid (CdTe-TGA QDs), a thiol-glucose-aptamer, and a Cy3-labeled aptamer. Due to the well-matched emission spectrum of the CdTe QDs and the absorption spectrum of Cy3, the FRET system decreased fluorescence intensity. However, glucose molecules quenched it when introduced to the system. The linear relationship between fluorescence intensity and glucose concentration was established with a detection limit of 7.72 × 10−9 M. The APTA sensor/Cy3 complex demonstrated excellent selectivity and specificity toward glucose and a high recovery rate of 96.00–101.11% in human serum and urine using the spiking method. The structural and morphological characteristics of the APTA sensor/Cy3 complex were confirmed by UV–visible spectroscopy, Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), atomic force microscopy (AFM), and dynamic light scattering (DLS) analyses.

The contamination of Ni2+ and Zn2+ has attracted increasing attention, not only because of the pollution it causes but also because of the potential risks it poses to human health. It is of great importance to explore sensitive and rapid analytical methods for the accurate detection of Ni2+ and Zn2+. This paper presents the design and synthesis of a peptide fluorescent probe, TPE-HN (TPE-Pro-Trp-His-Glu-Phe-Gln-NH2), coupled with a peptide to tetraphenylethylene (TPE). The aggregation-induced emission (AIE) effect has been employed to construct a rapid ‘turn-on’ assay for Ni2+and Zn2+ peptide fluorescent probes. The probe is capable of qualitatively detecting Ni2+ and Zn2+ in different buffer systems and can be distinguished by changes in buffer systems. The limit of detection for Ni2+ and Zn2+ in a 15% buffer solution was 9.613 mM (R2 = 0.9924), whereas the limit of detection for Ni2+ in a 20% buffer solution was 1.215 mM (R2 = 0.9922). The probe exhibits high sensitivity, high cell permeability and low biotoxicity, rendering it suitable for live-cell imaging under biological conditions. This demonstrates that TPE-HN is capable of detecting Ni2+ and Zn2+ in biological environments.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 2","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362294","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}

For this purpose, selected household materials can be used as radiation detectors by combining them with a portable reading device. Potassium dietary supplements based on potassium chloride in combination with a portable luminescence reader can be a promising dosimetry tool in such emergency situations. In the paper, results of unknown dose reconstruction based on tablets and pills with granules using optically stimulated luminescence (OSL) method are presented. Some OSL properties were examined: reproducibility of OSL as standard deviation of the OSL or sensitization of samples. Reconstructed doses were compared with dose delivered to BeO detectors. The results obtained for tablets were similar to BeO doses, while pill doses were differential, up to 37%. Overall reconstructed doses were on the same order of magnitude as BeO ones. The measurements were conducted using portable Helios reader due to its ability to measure samples of various shapes and sizes, which is not possible in other OSL reader. The development of mobile readers for emergency use is important because they enable rapid dose assessment on-site without the need for lengthy and expensive laboratory procedures.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 2","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143111863","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}
