The detection of physiological phosphates (PPs) is great importance due to their essential roles in numerous biological processes, but the efficient different PPs simultaneously remains challenging. In this work, we propose a fluorescence sensor array for detecting based on metal-ion-regulated gold nanoclusters (AuNCs) via an indicator-displacement assay. Zn2+ and Eu3+ are selected assemble with two AuNCs, resulting quenching or enhancing fluorescence. Based competitive interaction metal ions AuNCs PPs, will be recovered owing disassembly AuNC-metal ion ensembles. Depending PPs' distinct responses, four-channel was established. not only exhibits good discrimination capability eight kinds (i.e., ATP, ADP, AMP, GTP, CTP, UTP, PPi, Pi) linear discriminant analysis also enables quantitative single phosphate (e.g., ATP) presence interfering mixtures. Moreover, potential application present real samples cell lysates serum) successfully demonstrated performance. This work illustrates ion-regulated as new sensing platform differential well other disease-related biomolecules.

Abstract Food contaminants present a significant threat to public health. In response escalating global concerns regarding food safety, there is growing demand for straightforward, rapid, and sensitive detection technologies. Noble metal nanoclusters (NMNCs) have garnered considerable attention due their superior attributes compared other optical materials. These include high catalytic activity, excellent biocompatibility, outstanding photoluminescence properties. features render NMNCs promising candidates crafting nanosensors contaminant detection, offering the potential development of uncomplicated, swift, sensitive, user‐friendly, cost‐effective approaches. This review investigates based on NMNCs, including synthesis methodologies sensing strategies, applications in detecting contaminants. Furthermore, it involves comparative assessment performance. Ultimately, this paper imparts fresh perspectives forthcoming challenges. Hitherto, (particularly fluorescent) founded demonstrated exceptional capabilities realm detection. To enhance performance, future research should prioritize atomically precise synthesis, augmentation activity properties, high‐throughput multimode sensing, integration with microfluidic devices, optimization storage, shelf life, transportation conditions.

Nanoclusters are nanostructures consisting of few to tens atoms which have attracted great interest from the scientific community due their applications in a myriad fields, catalysis biomedical applications. Due discrete energy levels resulting ultrasmall size, nanoclusters exhibit distinctly different chemical, optical, and electrical properties compared with larger nanoparticle counterparts. Unlike previously reported dimensions (1–10 nm), typically single advantage (for example, high conductivity or optical properties), can be used as signaling and/or reaction-accelerating materials almost all sensing assays enhanced properties. among most promising luminescent emitters (electrochemiluminescent, fluorescent, chemiluminescent, colorimetry) quantum yield better biocompatibility than conventional emitters. Considering excelent biocompatibility, tailored modification, desirable electrochemical tunability, opened new horizons designing high-performance biosensing devices. In addition, they represent excellent photoelectrochemical behaviors improved functionality environmentally friendly traditional compounds. This review discusses recent advances nanoclusters, biosensing, current limitations, prospects overcome these challenges. The present study gives much brighter vision that one by particular advantages role developing frameworks.

Aggregation-induced emission (AIE) or aggregation-induced enhancement (AIEE) has endowed gold species with responsive fluorescent properties, favoring their potential applications in sensing, imaging, and therapy. However, it remains an interesting challenge to fabricate fluorophores both AIE AIEE effects. Herein, we presented highly luminescent Au(I) thiolate nanocomplex-based biosensors Zn2+ induced-AIE zeolite imidazolate framework (ZIF-8) induced-AIEE The nonemissive monovalent gold–glutathione complexes (AuI-SGs) were obtained synthesize the core–shell Zn2+/AuI-SG@ZIF-8 composites strong luminescence via coordination-assisted self-assembly strategy. By immobilizing GOx on surface of Zn2+/AuI-SG@ZIF-8, Zn2+/AuI-SG@ZIF-8/GOx exhibited effective responsiveness glucose, showing a "turn-off" detection model. mechanism study revealed that robust glucose sensing was attributed acid-stimulated degradation probe facilitated by H+ generated from oxidase (GOx)-catalyzed oxidation process.
