The single-luminophore-based ratiometric electrochemiluminescence (ECL) sensor coupling bidirectional regulator has become a research hotspot in the detection field because of its simplicity and accuracy. However, limited hinders further development. In this study, by leveraging robust predictive capabilities machine learning, we prepared an Fe-based metal-organic framework (FeMOF) as for modulating dual-emission ECL signals single luminophore first time. proof concept was demonstrated applying FeMOF to classical Ru(bpy)32+, results showed ability enhance cathode signal (Ecathode) inhibit anode (Eanode). As example, Tau protein (Tau) utilizing FeMOF/Ru(bpy)32+ system developed. incorporation effectively mitigated erratic fluctuations or minor discrepancies between two stronger correlation stability Ecathode/Eanode than before regulation. result, good analytical performance with limit low 3.38 fg mL-1 (S/N = 3). Moreover, it not only comparable test commercially available ELISA kit but also could well distinguish normal Alzheimer's disease (AD) patients (80% specificity 90% sensitivity). Thus, proposed strategy is promising be extended other luminophores MOFs, providing new path sensors.

Herein, a visual electrochemiluminescence (ECL) luminophore, 6-azido-2-thioxanthine-coated gold nanoclusters (ATT-Au NCs), was prepared efficiently in single step, followed by comprehensive characterization of their structural, optical, and ECL properties using diverse analytical methodologies. Concurrently, nanoparticles, dimers, nanorod (Au NR) dispersions, dimers (parallel perpendicular conformations) were synthesized via chemical reduction, DNA ligation, seed growth, electrostatic adsorption organic ligands, respectively. The finite difference time domain (FDTD) modeling subsequently employed to analyze the electromagnetic field distribution surrounding these revealing that parallel notably enhanced intensity. Based on this, we constructed novel biosensor harnessed surface-plasmon-coupled (SPC-ECL) resonance energy transfer (RET) between ATT-Au NCs Au NR dimers. sensor incorporated Cu2O nanoparticles (NPs) as quenching probes precisely induce RET, leading signal being switched "off". This dual enhancement strategy achieved high signal-to-noise ratio, facilitating sensitive detection microRNA-21 (miRNA-21) with linear range 1 fM–100 nM low limit 0.28 fM. work not only extends our understanding SPC effect application RET mechanism ECL, providing theoretical foundation for further advancements field, but also highlights its considerable potential applications biomedical research clinical diagnostics.

In this work, using Al-H3NTB-MOG with self-enhanced and aggregation-induced electrochemiluminescence (AIECL) performance as an efficient emitter, a biosensor based on Y-shaped multiregion dual-drive DNA walker was constructed for the sensitive detection of miRNA-141. Notably, 4,4',4″-nitrilotribenzoic acid (H3NTB) selected luminescent ligand ECL property co-reactive tertiary amine in its structure. Al3+ served central ion to coordinate H3NTB form three-dimensional porous gel structure, which restricted internal rotation vibration benzene molecules exhibited excellent AIECL property. More interestingly, N-2-hydroxyethylpiperazine-N'-ethane-sulfonic (HEPES) chosen system buffer, could not only stabilize test environment but also play co-reaction compensation role compensate consumption groups process, then significantly resulting better stability response. Besides, dynamic signal amplification established synergistic effect rolling cycle (RCA) process ionic cleavage at both ends nanostructure assembled by catalytic hairpin self-assembly (CHA) reaction. Specifically, two long chains abundant recognition regions were formed RCA reaction walker, simultaneously walk along predesigned tracks shear specific sites from directions, effectively improving efficiency. that way, realized miRNA-141 10 aM 1 nM range limit low 6.48 aM.
