Determination of diethylstilbestrol by enhancement of luminol–hydrogen peroxide–tetrasulfonated cobalt phthalocyanine chemiluminescence

Enhancement of chemiluminescence of the KIO4–luminol system by gallic acid, acetaldehyde and Mn2+: application for the determination of catecholamines

“…A common strategy to enhance the luminol-based CL emission involves the increased production of luminol radical, a key CL intermediate, by the reaction of luminol with other radicals or reactive oxygen species, such as substrate radicals, [20,21] superoxide anion O 2 − , [22,23] hydroxyl radical…”

“…uric acid, methanol, DMSO), and 1 O 2 (e.g. 1,4-diazabicyclo[2,2,2]octane, sodium azide, DMF, glutathione) [22,[25][26][27] were tested for their quenching effect on the CL emission. When various scavengers were added separately to the solutions containing KIO 4 O 2 are all critical for the CL enhancement.…”

Electrochemical Investigation of Carbon Paste Biosensor Bound with Natural Rubber Solution

“…If those can be optimized, it is clear that the detection limit will be much improved from the present state. Using the chemiluminescence method, J. Wang et al 18 obtained 6.42 × 10 -8 M as its detection limit and B. Tang 19 achieved 3.89 × 10 -10 M using the fluorimetric method. If we consider only the detection limit, the potentiostatic method can not compete with the spectroscopic method.…”

A novel chemiluminescent flow injection analysis of trace amounts of rutin by its inhibition of the luminol–hydrogen peroxide reaction catalyzed by tetrasulfonated colbalt phthalocyanine

“…In 1990, Hara et al first developed the application of metallophthalocyanine compounds as catalysts in the CL reaction between luminol and hydrogen peroxide, and furthermore as labeling reagents in CL immunoassay (22). Metallophthalocyanine has also been used for a wide range of applications in CL analysis (23)(24)(25).…”
