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
Rabies is a serious zoonotic disease in almost all warm-blooded animals and causes fatal encephalitis. The detection of rabies virus (RABV) is critical and remains a significant challenge. Herein, an electrochemiluminescence resonance energy transfer (ECL-RET) and electrochemical (EC) dual-mode immunosensor was developed for highly sensitive detection of RABV glycoprotein. Dendritic mesoporous silica nanoparticles (DMSNs) were employed to load Ru(bpy)32+ and to obtain ECL probes (Ru@DMSNs). Ru@DMSNs were decorated on the electrode surface, followed by the modification of the RABV antibody (Ab1). RABV was specifically recognized and captured by Ab1, causing the decline of the ECL signal due to the obstruction of electron transfer. Additionally, manganese oxide nanoparticles (MnOx) modified with Ab2 can further quench the ECL signal of Ru@DMSNs via the RET between Ru@DMSNs and MnOx. Meanwhile, MnOx can catalyze the oxidation of o-phenylenediamine (o-PD), generating a significant differential pulse voltammetry (DPV) signal as a second signal to monitor RABV glycoprotein concentration. Consequently, an immunosensor was developed to achieve dual-signal detection of RABV and improve reliability. Under the optimal conditions, detection ranges of 0.10 pg·mL-1 to 10 ng·mL-1 for ECL (with an 88 fg·mL-1 detection limit) and 1 pg·mL-1 to 2 ng·mL-1 for EC (with a 0.1 pg·mL-1 detection limit) were obtained for RABV detection. The reliability of this immunoassay was validated by eight brain tissue samples. The results were found to be compatible with the results of the real-time reverse transcription-polymerase chain reaction (RT-PCR) assay, indicating the potential applicability of this method for RABV diagnosis.

Abstract
The Stoeber reaction was used to grow silica microparticles in the presence of the fluorescent dye Tris(bipyridine)ruthenium (II) chloride. The diameter of the obtained particles varies from about 150 to 280 nm depending on the dye concentration. Using spectrofluorometry methods, concentration quenching of fluorescence of dye solutions was studied before and after growing the microparticles. It was found out that the concentration quenching of fluorescence decreases significantly after its incorporation into the silicon dioxide microparticles upon excitation in the short-wavelength region of the spectrum.

The recent advances in representative examples of ECL nanosenors in cancer diagnosis are highlighted, including high-throughput ECL analysis, in situ assay, visual ECL detection, single-cell imaging diagnosis, and so on. Finally, the challenges are featured based on the recent development of the ECL nanosensing system in the clinical diagnosis. The ECL nanosensors provide effective and reliable analytical methods and open new paths for cancer diagnosis. It is noteworthy that the prospects of the ECL nanosensing system in clinical diagnosis are instructive to the developments of other nanosensor research.

Abstract
A simple and convenient electrochemiluminescence immunoassay (ECLIA) has been developed by using gold nanoparticles (AuNPs) as both label and co-reactant. In this novel ECLIA, the detection antibodies labeled with AuNPs as co-reactant reacts directly with ruthenium complex to produce electrochemiluminescence (ECL), which avoids the weakness of luminophore as a label. The feasibility of the new method was investigated through the sandwich ECL immunosensor for the determination of human immunoglobulin (HIgG), and excitation of luminescence was respectively driven by linear sweep voltammetry and step potential. Under the optimal conditions, ECL intensity of the immunosensor increased with HIgG concentration in a wide range from 0.01 to 10.0 ng/mL and displayed linear response to logarithm of HIgG concentration. The results showed that the detection limit was 5 pg/mL, and the relative error was no more than 4.6% for the repeated measurements. The relative standard deviation was less than 2.9% for the determination of the standard sample, which can meet the requirement of ECLIA.

Abstract
A sensitively homogeneous electrochemiluminescence (ECL) method was developed for 5-hydroxymethylcytosine (5hmC) detection using TiO2/MoS2/g-C3N4/GCE as substrate electrode, where g-C3N4 was employed as the ECL active material, the MoS2 nanosheets were used as co-catalyst, and TiO2 was adopted as phosphate group capture reagent. To achieve the specific recognition and capture of 5hmC, the covalent reaction between -CH2OH and -SH was employed under the catalysis of HhaI methyltransferase, in which, -SH functionalized ferrocenedicarboxylic acid polymer (PFc-SH) was prepared as 5hmC capture reagent and ECL signal quencher. Then, based on the interaction between TiO2 and phosphate group of 5hmC, the target was recognized and captured on electrode, resulting in a decreased ECL response due to the quenching effect of PFc-SH. Under optimal conditions, the biosensor presented the linear range from 0.01 to 500 nM with the detection limit of 3.21 pM (S/N = 3). The steric effect on electrode surface is a bottle-neck issue restricting devised biosensors advancement. In this work, the reaction between 5hmC and PFc was carried out in the solution, which can avoid steric effect on electrode surface to keep the high activity of enzyme. In addition, the biosensor was successfully applied to detect 5hmC in genomic DNA of chicken embryo fibroblast cells and different tissues of rice seedlings.

Abstract
5-Hydroxymethylcytosine (5 hmC) is a novel epigenetic modification that plays an important role in mammalian nuclear reprogramming, regulation of gene activity, and initiation of DNA demethylation. In this paper, an electrochemiluminescence sensor was constructed for 5 hmC detection based on thiol functional Fe3O4 magnetic beads and covalent chemical reaction of -CH2OH in 5 hmC. First, Fe3O4 magnetic beads were prepared and modified with thiol. Then, 5 hmC was captured on the surface of the magnetic beads by the reaction between -CH2OH of 5 hmC and -SH of the thiol-functionalized Fe3O4 under the catalysis of DNA methyltransferase (M. HhaI). After that, through a series of reactions, phos-tag-biotin, avidin, and bis(hexafluorophosphate) (Ru (bpy)2 (phen-5-NH2) (PF6)2) (Ru) were further successively immobilized on the surface of the magnetic beads. More importantly, these reactions were carried out in a solution to ensure the activity of the biomolecules, and further to ensure that the reaction proceeded sufficiently. Finally, an ECL signal was generated by the introduction of Ru. The concentration of 5 hmC presented a good linear relationship with the ECL signal intensity in the range of 0.01-500 nM, and the detection limit was 2.86 pM. Moreover, we also used this method to study the 5 hmC content change in rice seedlings treated with antibiotics and heavy metal composite pollutants, and in chicken embryo fibroblast cell infected with and without avian leukosis virus subgroup J.
