Compared with Au@SNAzyme, SiO 2 –SNAzyme@ABEI higher catalytic activity, which can be applied chemiluminescence detection of miDNA-499.

the chemiluminescence (cl) arising from the reaction of bis(2,4,6-trichlorophenyl)oxalate (tcpo) with h2o2 in the presence of a novel blue fluorescer, furandicarboxylate derivative, has been studied. the relationship between the cl intensity and concentrations of peroxyoxalate, sodium salicylate, h2o2 and furandicarboxylate derivative as fluorescer has been investigated. kinetic parameters for ...

The effects of the 16-member macrolide spiramycin (2.5-80 mg/L) and the 14-member agent clarithromycin on the production of superoxide by activated human neutrophils were compared in vitro and related to membrane-stabilizing activity. Superoxide production was measured by lucigenin-enhanced chemiluminescence with N-formyl-L-methionyl-L-leucyl-L-phenylalanine (1 microM) as the stimulus, and memb...

Electrogenerated chemiluminescence (ECL) microscopy shows promise as a technique for mapping chemical reactions on single nanoparticles. The technique’s spatial resolution is limited by the quantum yield of emission and diffusive nature ECL process. To improve signal intensity, dyes have been coupled with plasmonic nanoparticles, which act nanoantennas. Here, we characterize optical properties ...

We studied the electrochemical and spectroscopic properties of a series of extended silole-based chromophores to understand the effect of structure on behavior. By changing the substituents attached to the chromophore, we observed large variations in luminescence quantum efficiency (ca. 0-0.6), lambdamax for absorbance and photoluminescence (PL), and radical ion stability. The differences are r...

The characteristic features of luminescence from solid polymers are compared with the emission from the isolated 'monomer'. The dominance of excimer emission in the solid enables this to be used for the characterization of polymer blends, relaxation processes and transport properties. These may also be studied by electronic energy transfer and the incorporation of a luminescent probe enables th...

The objective of this study was to investigate the relationship between the antimycobacterial properties of the antileprosy drug clofazimine and its stimulatory effect on the release of reactive oxidants by polymorphonuclear leukocytes by using a variety of phenazine derivatives. The effects of these compounds on myeloperoxidase-mediated iodination, luminol-enhanced chemiluminescence, and the r...
