These materials, are utilized for the fluorometric detection of Hg(II) and Cr(VI). Both the soluble N,S-doped CNDs and the aminosilica/N,S-doped CNDs exhibit two distinct emission spectral bands when the excitation wavelength is varied. The fluorescence of soluble N,S-doped CNDs at λex/λem = 390 nm/470 nm is quenched in the presence of both Hg(II) and Cr(VI); however, only Hg(II) quenches the fluorescence at λex/λem = 450 nm/553 nm. In contrast, only Cr(VI) quenches the fluorescence of aminosilica/N,S-doped CNDs at λex/λem = 380 nm/463 nm, while the fluorescence at λex/λem = 440 nm/538 nm remains unaffected. By exploiting the fluorescence quenching behavior of free and aminosilica-embedded N,S-doped CNDs, fluorescence-based probes are developed to selectively detect Hg(II) and Cr(VI). The limits of detection, defined as the concentrations corresponding to a signal-to-noise ratio of 3, are determined to be 0.04 and 0.06 μM for Hg(II) and Cr(VI), respectively. Further investigations reveal distinct quenching mechanisms for each system: the fluorescence quenching effect on N,S-doped CNDs by Hg(II) is attributed to a static mechanism, and the quenching of aminosilica/N,S-doped CNDs by Cr(VI) is ascribed to the inner filter effect.","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"5 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/anse.202500017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The probe detected Al3+ and As3+ ions when excited at 326 nm in an aqueous medium. The nonfluorescent HBIm exhibited a “turn-on” fluorescence response upon being treated with Al3+ (λem = 510 nm) and As3+ (λem = 499 nm) ions due to the chelation-enhanced fluorescence effect. The detection limits for Al3+ and As3+ are low and are found to be 0.38 and 2.37 nM, respectively. Furthermore, the binding constants for these ions are significantly high, 1.59 × 105 M−1 for Al3+ and 3.54 × 104 M−1 for As3+. The binding mechanism between HBIm and Al3+ and As3+ ions is supported by various techniques, including ESI-MS, Job's plot, 1H NMR, X-ray photoelectron spectroscopy, SEM-EDS, and density functional theory studies. The reversibility experiments are conducted using EDTA ions to develop the corresponding logic gates.

Herein, a cyclodextrin-based polymer sensor (Ech-CDP) is developed for real-time, visible detection of harmful methylene blue (MB) and methyl orange (MO) dyes in distilled and contaminated natural water samples. The sensor works through a competitive host-guest mechanism between sodium dodecyl sulphate (SDS) and Ech-CDP, altering liquid crystal alignment. Initially, SDS induces homeotropic ordering, which shifts to a tilted state upon binding with Ech-CDP. The presence of MB or MO displaces SDS, reverting the alignment and causing a visible bright-to-dark transition under polarizers. The sensor exhibits high selectivity, with detection limits of 0.03 mM for MB and 0.05 mM for MO in aqueous solutions, and 0.08 mM for MB and 0.26 mM for MO in real water samples, remains effective for 3 days, and is unaffected by pH variations between 4.8 and 9.1. Additionally, the sensor demonstrates an on–off switching capability, suggesting potential applications for molecular logic gates and advancing environmental monitoring techniques in dye-polluted waters.","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"5 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145135385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Once a regional tradition, these artisanal cigarettes are now the second most consumed type in the country. Tobacco products contain nicotine (NIC), a highly addictive substance linked to cardiovascular diseases. This study presents an electrochemical synthesis method for a reduced graphene oxide/silver–copper–hexacyanoferrate (rGO/AgCuHCF) composite, optimized for sensitive NIC detection. The optimized material is prepared using a 3:1 Ag:Cu ratio in an initial cyclic voltammetry step, followed by treatment with a pH = 7.0 ferricyanide solution, achieving a sensitivity of 13.0 nA L mol−1 via a 22 factorial design experiment. Microscopic analysis reveals uniformly distributed PBA particles over the wrinkled carbon support, while spectroscopic and diffraction techniques confirm distinct bimetallic PB analogue structural features from monometallic variants. Batch injection analysis-assisted amperometry with the rGO/AgCuHCF-modified electrode exhibits a linear current response for NIC between 5.0 and 2000.0 μmol L−1, achieving a superior sensitivity of 32.9 nA L mol−1 and a low detection limit of 0.9 μmol L−1. This sensor demonstrates viability and reliability for NIC detection in industrial and artisanal cigarettes tobacco samples.","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"5 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145135282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sophisticated characterizations, including XRD, XPS, TGA, FESEM, FT-IR, and Hirshfeld analysis, demonstrate high phase purity, thermal stability, robustness, presence of π–π stacking, and weak H-bonding in the framework. The MOF shows low detection limits for GSH (60.37 nM) and FA (9.77 μM) with fast response times (25 s for GSH, <2 min for FA). Biomarker GSH was detected in complex biological samples, including fetal bovine serum, vegetable, and human urine, with recovery rates between 81% and 89%. A smartphone-assisted GSH-sensing platform was proposed via RGB color variations of several sensor-analyte adducts. A 5-input, 4-output molecular logic gate was also demonstrated based on the sensor's spectroscopic response to varying GSH concentrations. FA detection was extended to fish, meat, and wastewater samples, with recoveries of 91–107%. DFT calculations revealed that analyte interactions restricted photo-induced electron transfer in the MOF, enhancing fluorescence phenomenon. These findings open new possibilities for MOF-based sensor technologies.","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"5 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145135211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Amynteo and Naoussa regions are included in the protected designation of origin (PDO) zones where differences in terroir are evident. These differences occur due to several factors, such as soil conditions of the cultivated vineyards, temperature, altitude, and climatic variations. Herein, 22 Xinomavro wines from Amynteo and Naoussa, produced with an identical vinification procedure are analyzed using ultra high performance liquid chromatography–trapped ion mobility spectrometry–quadrupole time of flight–mass spectrometry (UHPLC–TIMS–QTOF–MS) with reverse phase chromatography and negative ionization mode. The aim is to evaluate the impact of the geographical origin on their phenolic profile. Both target and non-target screening workflows are employed, leading to the identification and quantification of 26 phenolic compounds and the determination of 25 geographical origin biomarkers. Compounds like catechin and hydroxytyrosol are more abundant in samples from Naoussa while Amynteo is characterized by increased concentration of resveratrol and polydatin. All samples are correctly classified based on their geographical origin, achieving satisfactory, Q2 = 0.915 and R2 = 0.923, prediction ability results, developing a partial least-squares discriminant analysis model.","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"5 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/anse.202400120","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145135823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
