Chemiluminescence (CL)-based analytical methods utilize luminophores that need to be activated with an oxidizing agent to trigger CL emission. Despite its susceptibility to decomposition when exposed to external light or trace metals, hydrogen peroxide (H2O2) has been widely used to develop chemiluminescent methods due to the limited number of suit...

Transition-metal-based nanozymes show great potential for chemiluminescence (CL) detection due to their stability, excellent catalytic properties, good biocompatibility, and facile synthesis. In this study, bimetallic CoMoO 4 nanorods with high peroxidase activity were synthesized using a hydrothermal method, followed by calcination treatment. The...

1,4-Dithiothreitol (DTT), a highly water-soluble and well-known reducing agent for preservation and regeneration of sulfhydryl groups in biomedical applications, has been developed as an efficient and stable coreactant of lucigenin for the first time. DTT efficiently reacts with lucigenin to generate intense chemiluminescence (CL), eliminating the...

Electrochemiluminescence (ECL) has continued to receive considerable attention in various applications, owing to its intrinsic advantages such as near-zero background response, wide dynamic range, high sensitivity, simple instrumentation, and low cost. The ECL luminophore is one of the most significant components during the light generation process...

Vanadyl acetylacetonate, VO(acac)2, is a well-known environmentally friendly catalyst for aerobic oxidations. It has been exploited as an efficient co-reactant of luminol chemiluminescence (CL) in aqueous media for the first time. The luminol-VO(acac)2 system generates an intense CL and ascorbic acid can quench its CL remarkably. Based on the stron...

Dopamine (DA) is a very imperative neurotransmitter in our body, since it contributes to several physiological processes in our body, for example, memory, feeling, cognition, cardiovascular diseases, and hormone secretion. Meanwhile, tyrosinase is a critical biomarker for several dangerous skin diseases, including vitiligo and melanoma cancer. Most...

Since the concept of hybrid Li/Na-ion batteries (HLNIBs) was proposed, many cathode materials with excellent performance and low cost have been studied. However, in HLNIBs, mixed cationic electrolyte is formed as Na⁺ is extracted from the cathode, resulting in relatively complicated and unstable electrochemical performance, especially for the half-...

Diabetic nephropathy (DN) refers to kidney damage caused by diabetes and is one of the major microvascular complications of diabetes. This disease has a certain degree of concealment in the early stage, with clinical symptoms appearing later and a higher mortality rate. Therefore, the detection of early biomarkers for DN is of great importance in r...

Imaging technologies based on chemiluminescence (CL) and bioluminescence (BL) have seen a tremendous growth in the past decade due to their extensive contributions to biochemical analysis and biomedical science. CL and BL imaging technologies have many advantages over commonly used imaging techniques (such as fluorescence and electrochemical system...

Sodium-ion batteries (SIBs) are regarded as promising alternatives to lithium-ion batteries (LIBs) in the field of energy, especially in large-scale energy storage systems. Tremendous effort has been put into the electrode research of SIBs, and hard carbon (HC) stands out among the anode materials due to its advantages in cost, resource, industrial...

Tris(4,7'-diphenyl-1,10-phenanthroline) ruthenium (II) dichloride [Ru(dpp)3²⁺] was used for the first time to construct a regenerable electrochemiluminescence (ECL) sensor. The Ru(dpp)3²⁺-modified carbon paste electrode (CPE) showed several unique features in comparison with commonly studied Ru(bpy)3²⁺-modified electrodes. On the one hand, a quite...

Doping plays a crucial role in electrochemiluminescence (ECL) due to the following: (1) Modulation of electronic structure, alteration of the surface state of nanoparticles (NPs), providing effective protection from the surrounding environment, thereby leading to ECL emitters with exceptional properties including tunable spectra, high luminescence...

Life‐threatening diseases, such as hepatitis B, pneumonia, tuberculosis, and COVID‐19, are widespread due to pathogenic bacteria and viruses. Therefore, the development of highly sensitive, rapid, portable, cost‐effective, and selective methods for the analysis of such microorganisms is a great challenge. Microchip electrophoresis has been widely u...

The mesh-type USB piezoelectric ultrasonic transducer (USB-PUT) used in household humidifiers and inhalation therapy devices is very cheap, small, and energy saving. It holds great promise for sonochemistry. However, the microtapered apertures in the center of the stainless steel substrate of mesh-type USB-PUT can lead to rapid atomization of solut...

Oxamic hydrazide (OHA) was utilized as an efficient coreactant of Ru(bpy) 3 2 + for the first time, which can dramatically increase the electrochemiluminescence (ECL) intensity of Ru(bpy) 3 2 + on glassy carbon electrode (GCE). 4-nitrobenzaldehyde (4-NBA), a nitroaromatic compound, has mutagenic and carcinogenic toxicity on humans' genome and cause...

The persistent reports on the indiscriminate contamination of foodstuffs with inedible chemicals for economic gains and the high cost of the existing analytical methods for their detection make it necessary to develop simple and cheaper methods for the immediate detection of those toxic substances. Here, we report a fast and highly sensitive electr...

Isatin is an endogenous indole derivative that has been reported to possess various pharmacological and therapeutic activities of clinical importance. To date, isatin has been detected mainly by mass spectrometry. Here, we report for the first time the intense anodic electrochemiluminescence (ECL) of tris(2,2’‐bipyridyl)ruthenium(II) with isatin as...

Herein, we report luminol-silicotungstic acid (STA) chemiluminescence (CL) for the first time. The luminol-STA system gave remarkable CL enhancement (65 times) over the known classical luminol-H2O2 system because of the generation of strong oxidizing agent tungsten trioxide from STA. Based on the quenching effect of uric acid, the new CL system is...
