In this study, we found that iodophenol blue can enhance the weak chemiluminescence (CL) of luminol–H2O2 system. With the aid of CL spectral, electron spin resonance (ESR) spectral measurements and studies on the effects of various free radical scavengers on the iodophenol blue-enhanced luminol–H2O2 system, we speculated that iodophenol blue may react with H2O2 and oxygen to produce oxidizing radical...
A polydimethylsiloxane (PDMS) microfluidic chemiluminescence (CL) immunodevice for sensitive detection of human immunoglobin G (IgG) with the signal amplification strategy was developed in this work. The immunodevice was prepared by covalently immobilizing capture antibodies (Abs) on the silanized microchannel of microfluidic chip. Gold nanoparticles (AuNPs) functionalized with a high molar ratio...
A chemiluminescence resonance energy transfer (CRET) platform was developed for sensitive and label-free detection of protease by using trypsin as a model analyte. In this CRET platform, bis(2,4,6-trichlorophenyl)oxalate–hydrogen peroxide chemiluminescence (CL) reaction was utilized as an energy donor and bovine serum albumin (BSA)-stabilized gold nanoclusters (Au NCs) as an energy acceptor. The BSA-stabilized...
A rapid and sensitive flow method, based on the combination of on-line solvent extraction with reversed micellar mediated chemiluminescence (CL) detection using rhodamine B (RB), was investigated for the selective determination of Au(III) and Ga(III) in aqueous solutions. 2.0M HCl was the optimum for extracting Au(III) while a 5.0M HCl solution containing 2.5M LiCl was selected as an optimum acidic...
Bromophenol red, known as chemical indicator, was found to act as a novel potent signal enhancer of the peroxidase-catalyzed luminol–H2O2 chemiluminescent (CL) reaction. It was found interestingly that bovine serum albumin (BSA) played a role in the enhanced chemiluminescent reaction (ECR). The addition of 2.5mgmL−1 BSA into bromophenol red-enhance CL system showed 36 times stronger CL signal than...
Aptamers are analogous to antibodies in their range of target recognition. G-quadruplex DNAzymes exhibit peroxidase-like activity toward certain specific reactions. Despite aptazyme sensors, based on aptarmer and DNAzyme conjugates, have the potential to replace many conventional immune-biosensors; the mechanism concerning high background interference has scarcely been discussed. In this work, by...
In this paper, a new chemiluminescence (CL) strategy was constructed for the determination of physiological thiols by using an isoluminol labeled nano-probe. The amino group on the surface of the magnetic beads (MBs) were converted into pyridyl disulfide groups by treatment with N-succinimidyl-3-(2-pyridyldithio)propionate (SPDP), in the meantime, isoluminol and thiolated signal DNA were labeled on...
Two chemiluminescence-microfluidic (CL-MF) systems, e.g., Ce(IV)–rhodamine B (RB) and Ce(IV)–rhodamine 6G (R6G), for the determination of the total phenolic content in teas and some sweeteners were evaluated. The results indicated that the Ce(IV)–R6G system was more sensitive in comparison to the Ce(IV)–RB CL system. Therefore, a simple (CL-MF) method based on the CL of Ce(IV)–R6G was developed, and...
A novel chemiluminescence (CL) system is introduced based on the oxidation of carminic acid by KMnO4 in acidic conditions. CdS quantum dots (QDs) were synthesized using a facile hydrothermal method which efficiently enhanced the intensity of the CL system. A possible mechanism for the proposed system is presented using the kinetic curves, CL spectra, photoluminescence (PL), and ultraviolet–visible...
A new sensitized chemiluminescence (CL) was developed to broaden the analytical application of KIO4–H2O2 system. The nitrogen doped carbon dots (N-CDs) dramatically boosted the CL intensity of KIO4–H2O2 system which was further enriched by basic medium. In light of EPR analysis, free radical scavenging studies and CL spectra the detail mechanism for the enhancement was conferred in the presence of...
A chemiluminescent method for nitrite detection was developed on microfluidic chip. Carbon dots-NaNO2− acidified H2O2 system was adopted. Chemiluminescence (CL) spectrum of this system was detected. The radiative recombination of hole-injected and electron-injected carbon dots explained their CL property. Spiral microchannels were designed on the microfluidic chip to allow enough reaction time for...
