Dual-readout fluorescence quenching immunochromatographic test strips for highly sensitive simultaneous detection of chloramphenicol and amantadine based on gold nanoparticle-triggered photoluminescent nanoswitch control

Jincheng Xiong et al.

Summary: A novel fluorescence quenching immunochromatographic test strip (FQICTS) was developed for simultaneous detection of chloramphenicol (CAP) and amantadine (AMD) using a combination of gold nanoparticles (AuNPs) and highly luminescent gold nanoclusters (AuNCs) as the quencher/donor pair. The FQICTS showed good linearity for CAP and AMD detection with low limits of detection. The strip's turn-on mode exhibited high recovery and good performance.

Identifying Luminol Electrochemiluminescence at the Cathode via Single-Atom Catalysts Tuned Oxygen Reduction Reaction

Hongyin Xia et al.

Summary: In this study, the relationship between intrinsic oxygen reduction reaction (ORR) activity and electrochemiluminescence (ECL) behavior was explored using single-atom catalysts (SACs). By combining electrochemical ORR catalyzed via SACs and chemical oxidation of luminol, the traditionally neglected cathodic ECL emission of luminol was significantly enhanced. This work is important for guiding the development of an amplified sensing platform through rational tailoring of the ORR activity of SACs and potential-resolved ECL assays based on high-efficiency cathodic ECL.

Zhimin Weng et al.

Summary: This study proposes a novel AuNC-based ECL sensing platform and explores the regulation mechanism of electron transfer on ECL. By investigating the ECL quenching effect of OM-AuNCs under the influence of Cu2+, it is found that the ECL intensity of OM-AuNCs is affected by the electron transfer process, enabling sensitive detection of Cu2+ in a low concentration range without the need for amplification techniques. This study enriches the application of ET-mediated ECL and promotes a more rational design of ECL sensors.

Summary: Electrochemiluminescence (ECL) plays a key role in analysis and sensing, but its application is limited by a lack of highly tunable luminophores. The authors demonstrate the design of highly efficient ECL luminophores of covalent organic frameworks (COFs) in aqueous media by simultaneously restricting the donor and acceptor to the COFs' electron configurations and constructing charge transport networks through olefin linkages.
