“…Thus, various chemiluminescence (CL) systems have received considerable attention in the past years. To further improve the sensitivity of CL assays, various catalysts have been investigated, including metal nanoclusters [1], metallic nanoparticles (in particular noble metal nanoparticles) [5,6], metal oxide nanoparticles [7,8], carbon dots [9][10][11], layered double hydroxide (LDH) [4,12], quantum dots [13,14], and LDH-quantum dot nanocomposites [15].…”

Various analytical applications of metal-organic frameworks (MOFs) have been rapidly developed in the past few years. However, the employment of MOFs as catalysts in chemiluminescence (CL) analysis is rare. Here, for the first time, we found that MIL-53(Fe) MOFs could significantly enhance the CL of luminol in the presence of HO in an alkaline medium. The CL intensity in the luminol-HO-MIL-53(Fe) system was about 20 times higher than that in the luminol-HO system. Moreover, the XRD pattern of MIL-53(Fe) after CL reaction was almost the same as that of the original MIL-53(Fe), confirming the catalytic role of MIL-53(Fe) in the luminol-HO-MIL-53(Fe) system. The possible mechanism behind the enhancing phenomenon was discussed based on the results from the CL spectra, FL probe experiments, and active oxygen species measurements. By coupling with the glucose oxidase-based catalytic oxidation reaction, a sensitive and selective CL method was developed for the detection of glucose. There is a linear relationship between the logarithm of CL intensity and the logarithm of glucose concentration in the range from 0.1 to 10 μM, and a detection limit of 0.05 μM (S/N = 3) is obtained. The proposed method has been applied to the determination of glucose in human serum samples with satisfactory results. Graphical abstract MIL-53(Fe) MOFs are found to greatly enhance the chemiluminescence emission of the luminol-HO system, and this finding resulted in a new chemiluminescence method for biosensing of glucose when coupled with the glucose oxidase.

“…The determination of hydrogen peroxide in biological systems and environment is of tremendous significance due to its effects on the ecosystem and the human health (Ahmed et al, 2012;Wang et al, 2011). Hydrogen peroxide advices as a "substance generally recognized as safe (GRAS)" reagent for food with the mentioned concentration limit value of 80 ppm (Kumar et al, 2012).…”

“…High concentrations of H 2 O 2 would cause irritation to dyes and shin, it affects human health [2]. On the other hand, the determination of H 2 O 2 concentration is important in food [3], clinical [4] and environmental applications [5]. There are many methods which can be used for the quantitative analysis of H 2 O 2 in solution, such as electrochemical method [6][7][8] and spectroscopy [9][10][11][12][13][14].…”

In this paper, the multicolor photoluminescence carbon quantum dots (CQDs) have been synthesized by one step hydrothermal method to analyze hydrogen peroxide (H 2 O 2 ). These CQDs exhibited multicolor emission under a single wavelength excitation for the quantification of H 2 O 2 . Using an LED with a central wavelength of 365 nm as the excitation source, it is shown that the red emission CQDs capable of detecting H 2 O 2 over the linear range of 0-88.2 mM and the H 2 O 2 sensitivity of wavelength shift to changes in the H 2 O 2 concentration was found to be 0.18 nm/mM. These results of the optical sensing method can be used in practice detection of H 2 O 2 and could offer a new approach for developing a new biosensor. The CQDs exhibit good emission property and high stability, as well as excitation-independent emission behavior. Moreover, it is attractive that CQDs can be used as an effective fluorescent probe for the detection of H 2 O 2 with linear Stern-Volmer plot and wavelength shift in an aqueous solution.
