Peroxynitrite-induced luminol chemiluminescence [PDF]

Biochemical Journal, 1993
Vascular endothelial cells, smooth muscle cells, macrophages, neutrophils, Kupffer cells and other diverse cell types generate superoxide (O2.-) and nitric oxide (.NO), which can react to form the potent oxidant peroxynitrite anion (ONOO-). Peroxynitrite reacted with luminol to yield chemiluminescence which was greatly enhanced by bicarbonate.

COMPARISON OF COLORIMETRIC AND CHEMILUMINESCENT ELISA TESTS FOR DETECTION OF IgG ANTIBODIES TO HUMAN EPO IN THE SERA OF EXPERIMENTAL ANIMALS

Медицинская иммунология, 2018
Production of antibodies to erythropoietin-stimulating drugs is an important problem of therapy with recombinant human erythropoietin (EPO). It leads to changes in the pharmacokinetic profile and decreased therapeutic efficiency. Upon long-term treatment

Light enhanced electrochemistry and electrochemiluminescence of luminol at glassy carbon electrodes

Electrochemistry Communications, 2019
We report in this work the enhancement effect of light irradiation on the electrochemistry and electrochemiluminescence (ECL) of luminol at the bare glassy carbon electrode (GCE). Light irradiation on the GCE surface induced the formation of hot electron-

On-line Mass Spectrometric Characterization of Key Intermediates in Luminol Electrochemiluminescence [PDF]

Zhipu Xuebao
Due to the low oxidation potential and high electrochemiluminescence (ECL) quantum yield, Luminol has been widely applied in analytical and detection fields, especially in immunoassay, food safety and environmental monitoring. However, there is a lack of

Deciphering electrochemiluminescence generation from luminol and hydrogen peroxide by imaging light emitting layer

Fundamental Research, 2022
Electrochemiluminescence (ECL) of luminol is a luminescence process that proceeds in the presence of reactive oxygen species (e.g. hydrogen peroxide (H2O2)) at a suitable electrode potential, the reaction mechanism of which is complicated and remains ...

Luminol Doped Silica-Polymer Sensor for Portable Organic Amino Nitrogen and Ammonium Determination in Water

Separations, 2021
We propose a portable sensor, obtained by embedding luminol into the tetraethylorthosilicate/trietoxymethylsilane (TEOS/MTEOS) composite, for the quantitative determination of organic amino nitrogen and ammonium in water with the goal of achieving low ...

Determination of Picogram Levels of Diacerein in a Pharmaceutical Formulation by Flow-Injection Chemiluminescence

MATEC Web of Conferences, 2017
A simple, sensitive and inexpensive method for determination of diacerein by flow-injection chemiluminescence was proposed, based on the quenching effect of diacerein on the luminol-protein (bovine serum albumin, BSA) reaction.
