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...

Abstract A new method to synthesize complexes of the type [(CNC)Ru II (NN)L] n+ has been introduced, where CNC is a tridentate pincer composed two (benz)imidazole derived NHC rings and pyridyl ring, NN bidentate aromatic diimine ligand, L=bromide or acetonitrile, n=1 2. Following this series six synthesized characterized by spectroscopic, analytic, crystallographic, computational methods. Their...

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.

objective: the anxiety profile in the stimulant-sensitized animals is not clear. thus, this study was conducted to elucidate the effects of acute and chronic administration of methamphetamine (meth) on the anxiety profile. the aim of this study was to examine whether meth-sensitized rats would show an increase in the expression of anxiogenic-like behaviors and to determine whether a low dose of...
