The electrochemistry and electrogenerated chemiluminescence (ECL) of a series of europium chelates, cryptates, and mixed-ligand chelate/cryptand complexes were studied. The complexes were of the following general forms:  EuL(4)(-), where L = β-diketonate, a bis-chelating ligand (such as dibenzoylmethide), added as salts (A)EuL(4), where A = tetrabutylammonium ion or piperidinium ion (pipH(+)); ...

Coumarin C343 (C(16)H(15)NO(4)), a dye used to enhance the weak chemiluminescence associated with lipid peroxidation, was conjugated to silica nanoparticles and entrapped in a sol-gel matrix to produce a nanosensor capable of enhancing low-level chemiluminescence by approximately 100%.

The stimulation of neutrophils by formylmethionyl-leucyl-phenylalanine results in a bimodal luminol-dependent chemiluminescence pattern. We observed, however, only a single peak chemiluminescence pattern in the response to the peptide when we used lucigenin as an amplifying substance. We suggest that lucigenin, the larger molecule, (510 daltons; luminol is 177 daltons) only exerts an extracellu...

Herein, we report a facile strategy for the synthesis of dual-functionalized graphene hybrids (A-H-GNs) based on interactions among graphene, N-(aminobutyl)-N-(ethylisoluminol) (ABEI) and hemin. The multilayers of a chemiluminescence reagent (ABEI) and a catalyst (hemin) were accumulated on the graphene surface, resulting in high chemiluminescence performance, good solubility and stability in a...

Hydroxylamine-O-sulfonic acid, a versatile reagent for organic synthesis, has been explored as an effective coreactant for luminol chemiluminescence. Co(2+) can dramatically enhance the chemiluminescence of this system. The sensitive detection of Co(2+), luminol and HOSA, including highly selective Co(2+) detection, is achieved.
