Summary: A catalyst-free co-reaction luminol-H2O2-K2S2O8 chemiluminescence (CL) system was developed, which exhibited long-life and high-intensity emission lasting for 6 hours. The mechanism of persistent and intense emission was discussed based on CL spectra, cyclic voltammetry, electron spin resonance (ESR), and the effects of radical scavengers. A CL-based method for the detection of ALP was established with good linearity and a low limit of detection. This method was successfully applied to detect ALP in human serum samples.

Summary: In this study, vanillin was found to efficiently catalyze hydrogen peroxide to produce reactive radicals and accelerate the chemiluminescence signal of luminol-hydrogen peroxide. By combining with beta-CD, the chemiluminescence intensity was further enhanced. Based on the catalytic and stabilizing functions, a low-cost, rapid, and simple chemiluminescence sensor was developed for the detection of vanillin.

Summary: Cathodic electrochemiluminesence (ECL) microscopy based on luminol analog L012 utilizes multiwalled carbon nanotubes (MWCNTs) as coreactant accelerators to convert oxygen and H2O2 into reactive oxygen species. The produced ROS oxidizes L012 to emit bright cathodic ECL illumination, enabling the imaging of nanotubes and nucleolin on tumor cells. By modifying MWCNTs with AS1411 aptamers, label-free ECL imaging of nucleolin on plasma membranes was achieved, providing a universal approach in single nanomaterial and single-cell imaging.

Summary: Mesoporous cobalt oxides have important applications due to their exceptional properties. In this study, mesoporous Co3O4 NPs with different porosity were successfully synthesized through a sonochemical process. The synthesized NPs were characterized using XRD, BET, and TEM. The catalytic effect of the Co3O4 NPs in the luminol-H2O2 chemiluminescence system was studied, and the system was used to detect and measure H2O2 and glucose under optimal conditions. The proposed method showed a good linear relationship and excellent LOD for both H2O2 and glucose.

Summary: In this study, a detection method combining ion-chromatographic separation, photochemical conversion, and chemiluminescence was developed for the sensitive detection of NO2- and NO3-. The method showed low detection limits (0.01 and 0.03 μM) and wide linear ranges (0.010-2.0 and 0.10-3.0 μM) for NO2- and NO3-. The results obtained from seawater analysis using this method were consistent with a reference method. The high sensitivity of the chemiluminescence technique used in this method has the potential to detect NO2- and NO3- at picomolar concentrations, making it an innovative technology for various sample types.

Summary: Chemiluminophores generate wide-band light emission through a chemical reaction without external light source. Plasmonic nanoparticles can enhance chemiluminescence quantum yield by accelerating radiative decay rate, while the catalytic action of metallic surface can increase the chemical reaction rate. Using an inert spacer layer on a silver metasurface may favor an electrodynamic mechanism for moderate chemiluminescence enhancement.

Summary: It was found that 2,3-dimethyl maleic acid (DMMA) can enhance the chemiluminescent reactions of luminol-H2O2, with the strongest enhancement observed using polyethyleneimine-templated gold nanoclusters (PEI-Au NCs) as the catalyst. The addition of DMMA increased the CL signal of the PEI-Au NCs-catalyzed reaction by about 630-fold, resulting in a flash-type CL profile. Mechanism studies revealed that the luminophore in the excited state was 3-aminophthalate anions (3-APA*), and superoxide radical (O-2(center dot-)) played a crucial role in the CL process. Under optimized conditions, the detection limit of PEI-Au NCs was significantly improved with the addition of DMMA. The catalytic activity of biotinylated PEI-Au NCs in the DMMA-enhanced luminol system was similar to PEI-Au NCs, indicating their potential for bioanalysis platforms. This research explores the application of the DMMA-enhanced luminol-H2O2 system to the detection of sequence-specific DNA related to hepatitis B virus (HBV), achieving superior sensitivity compared to reported methods.
