Abstract
The global spread of environmental biological pollutants, such as antibiotic-resistant bacteria and their antibiotic resistance genes (ARGs), has emerged as a critical public health concern. It is imperative to address this pressing issue due to its potential implications for public health. Herein, a DNA paperclip probe with double-quenching function of target cyclic cleavage was proposed, and an electrochemiluminescence (ECL) biosensing platform was constructed using Ti3C2 MXene in-situ reduction growth of Au NPs (TCM-Au) as a coreactant accelerator, and applied to the sensitive detection of ARGs. Thanks to the excellent catalytic performance, large surface area and Au-S affinity of TCM-Au, the ECL performance of CdS QDs have been significantly improved. By cleverly utilizing the negative charge of the paperclip nucleic acid probe and its modification group, double-quenching of the ECL signal was achieved. This innovative approach, combined with target cyclic amplification, facilitated specific and sensitive detection of the mecA gene. This biosensing platform manifested highly selective and sensitive determination of mecA genes in the range of 10 fM to 100 nM and a low detection limit of 2.7 fM. The credible detectability and anti-interference were demonstrated in Yangtze river and Aeration tank outlet, indicating its promising application toward pollution monitoring of ARGs.

Abstract
As is common knowledge, a strong electrochemiluminescence (ECL) signal is required to ensure the high sensitivity of trace target detection. Here, a dual signal amplification strategy by integrating of perovskite and photonic crystal was fabricated for quantitative synthetic cannabinoids (AB-PINACA) detection based on Zr-connected PTCA and TCPP (PTCA-TCPP) with excellent ECL performance as luminophores. On the one hand, the co-reaction accelerator perovskite (LaCoO3) improved the effective electroactive area of the electrode and promoted the decomposition of K2S2O8, resulting in a stronger ECL signal value. On the other hand, polystyrene inverse opal (PIOPCs) formed after the swelling of PS microspheres not only taken advantage of the light scattering effect and excellent catalytic property of photonic crystals to amplify the ECL signal, but also could be used as a binder to fix LaCoO3 and PTCA-TCPP on the electrode surface to generate unprecedented ECL response and stable ECL signals. Subsequently, the detection substance AB-PINACA was loaded on the electrode surface via the amide bond with the luminophores PTCA-TCPP, thus quenching the ECL signal, so as to realize the sensitive detection of synthetic cannabinoids. Under the optimal conditions, the proposed sensor achieved highly sensitive AB-PINACA detection with a dynamic range from 1.0 × 10-12 to 1.0 × 10-3 g/L and the detection limit was 1.1 × 10-13 g/L, which had great application potential in the detection of synthetic cannabinoids.

Abstract
Electrocheluminescence analysis amplified by coreaction accelerators has experienced breakthrough in ultrasensitive detection of biomarkers. Herein, a highly efficient coreaction accelerator, two-dimensional layered MoSe2 nanosheets loaded with gold nanoparticles (AuNPs@MoSe2 heterostructure), is proposed to enhance the ECL efficiency of Ru(bpy)32+/tripropylamine (TPrA) system. The presence of AuNPs avoids the aggregation of MoSe2 nanosheets, and improves the electrical conductivity of modified surface. The AuNPs@MoSe2 modified electrode also provides a large area for loading of abundant capture probe. MoSe2 as an electroactive substrate can remarkably accelerate the generation of TPrA•+ radicals to react with electrooxidized Ru(bpy)32+, which achieves about 3.4-fold stronger ECL intensity. Thus, an enhanced ECL immunoassay method can be achieved after Ru(bpy)32+-doped silica nanoparticle labeled antibody (Ab2-Ru@SiO2) is captured to the modified electrode via immunological recognition. Using methylated DNA as a target, the immunosensor was prepared by binding capture DNA on AuNPs@MoSe2 modified electrode to successively capture the target, anti-5-methylcytosine antibody (anti-5mC) and Ab2-Ru@SiO2. The proposed strategy could detect 0.26 fM 5 mC (3σ) with a detectable concentration range of 1.0 fM - 10 nM at methylated DNA. This immunosensor showed excellent selectivity, good stability and reproducibility, and acceptable recovery, indicating the broad prospects of the novel coreaction accelerator in clinical diagnosis.

Abstract
Herein, we fabricated a label-free ECL immunosensor for aflatoxin B1 (AFB1) detection. In this system, a small organic aggregation-induced electrochemiluminescence luminophore, 2,5-di-tetraphenylethylene-ylthiazolo [5,4-d] thiazole, was designed, named TPETTZ. Polyaniline-wrapped TiO2 nanoparticles (PANI/TiO2 NPs) complex was synthesized through one-step in situ oxidation polymerization of aniline, and performed excellent electrical conductivity and abundant amino groups. As an ECL accelerator, TiO2 nanoparticles (TiO2 NPs) promoted the oxidation of tri-n-propylamine (TPA) to generate more TPA•; in addition, it also acted as a donor to improve the ECL intensity of TPETTZ (acceptor) through electrochemiluminescence resonance energy transfer (ECL-RET). Encouraged by the above, under the existence of TPA, TPETTZ displayed a strong and continuously stable ECLanode signal due to the introduction of PANI/TiO2 NPs. Therefore, the immunosensor was constructed for AFB1 detection based on the quenching effect of target on the ECL signal, and a linearly decreasing ECL signal was obtained as the increasement of AFB1 in the range of 75 fg/mL to 100 ng/mL, with a lower detection limit of 27.5 fg/mL. Moreover, the as-prepared sensing platform performed a satisfactory anti-interference, stability, and reproducibility, and appeared a good accuracy in walnut sample analysis, presenting a promising application in the future.

Abstract
A novel biosensor was developed on the basis of Ru(dcbpy)(bpy)22+/tripropylamine (TPrA)/TiO2 nanocrystallines (TiO2 NCs) as efficient electrochemiluminescence (ECL) ternary system and enzyme-driven double-site DNA walker as signal amplification strategy for the sensitive detection of carcinoembryonic antigen (CEA). Specifically, coreaction accelerator anatase TiO2 NCs with catalytic activity could accelerate the oxidization of TPrA for prominently stimulating the ECL performance of Ru(dcbpy)(bpy)22+/TPrA system to achieve the "signal on" state. Subsequently, numerous double-site walker DNA, converted from the target (CEA)-induced protein-aptamer cycle amplification, would trigger the detachment of Ru(dcbpy)(bpy)22+ to reach the state of "signal-off". Benefiting from the above advantages, the developed ECL biosensor achieved outstanding sensitivity with a linear range from 500 pg/mL to 50 fg/mL and a detection limit down to 10.5 fg/mL. More importantly, the proposed strategy opens a new path for employing the ECL ternary system for sensitive detection of biomolecules and disease diagnosis.

Abstract
In this work, a high-efficiency electrochemiluminescence (ECL) ternary system was constructed for ultrasensitive assay of insulin based on hollow porous graphitic carbon nitride (HP-C3N4) as novel luminophore, S2O82- as coreactant and tri-metallic AuPtAg as coreaction accelerator. Specifically, in comparison with C3N4-based bulk nanomaterials, the as-prepared HP-C3N4 exhibits high luminous efficiency though decreased inner filter effect and minimized inactive ECL emitter. Noteworthy, tri-metallic AuPtAg, possessing the superiority of Au, Pt and Ag, was first used as coreaction accelerator to significantly enhance ECL intensity of HP-C3N4 and S2O82-. As a consequence, with the resultant ECL ternary (HP-C3N4/S2O82-/AuPtAg) system as aptasensing platform, a high-intense initial ECL signal was achieved. Subsequently, ferrocene-labeled quenching probe (Fc-HP2) as ECL quencher was used to quench the initial signal and achieve the low-background noise. Eventually, in the presence of insulin, the target-induced triple-helix molecular switch and Nb.BbvCI-assisted DNA walker amplification were executed to recover a strong ECL signal by releasing Fc-HP2 from the electrode surface. As expected, the constructed aptasensor presents an excellent sensitivity and selectivity for detecting insulin range from 0.05 pg mL-1 to 100 ng mL-1 with a detection limit of 17 fg mL-1. This work provides a new avenue for developing highly efficient HP-C3N4 based ECL ternary system as well as ultrasensitive ECL aptasensors for bioanalysis.
