Um método simples e sensível baseado na análise de quimiluminescência por injeção em fluxo acoplado ao complexo luminol-Ag(III) foi desenvolvido para se determinar ácido úrico (UA) em urina humana. O método se baseia na reação de quimiluminescência (CL) do luminol com Ag(III) em solução alcalina, sendo que o UA da urina aumenta dramaticamente as intensidades CL. Em condições ótimas, a intensida...

Luminol, leuchomalachite green, phenolphthalein, Hemastix, Hemident, and Bluestar are all used as presumptive tests for blood. In this study, the tests were subjected to dilute blood (from 1:10,000 to 1:10,000,000), many common household substance, and chemicals. Samples were tested for DNA to determine whether the presumptive tests damaged or destroyed DNA. The DNA loci tested were D2S1338 and...

By designing a novel electrolytic flow cell, the strong oxidant BrO2 was electrogenerated on-line in KBr solution and its concentration could be readily adjusted on-line with the flow-injection technique and an electrochemical method. The chemical reaction between BrO2 and luminol in alkaline medium is accompanied by weak emission of light due to chemiluminescence (CL). It was found that the is...

The detection of chemiluminescence of human polymorphonuclear leukocytes activated by the nonparticulate stimulus phorbol myristate acetate required the presence of suitable substrate, such as protein or luminol, in the reaction medium. This substrate requirement was met by the addition of human serum or various proteins, such as bovine serum albumin, lysozyme, egg albumin, or immunoglobulin, t...

This paper reports a microchip with an integrated passive micromixer based on chaotic advection. The micromixer with staggered herringbone structures was used for luminol-peroxide chemiluminescence detection. The micromixer was examined to assess its suitability for chemiluminescence reaction. The relationship between the flow rate and the location of maximum chemiluminescence intensity was inv...

Background . Ionizing radiation is an effective antitumor therapy, but it has a serious negative effect on the immune system requiring use of reaction prevention and reduction methods. Neutrophils are sensitive element both in interaction with tumor tissue response to injury. Aim To evaluate functional activity peripheral blood neutrophils by chemiluminescent analysis patients anorectal cancer ...
