We describe a novel platform technology for both significantly enhancing and obtaining chemiluminescence signatures "on-demand", subsequently named Microwave-Triggered Metal-Enhanced Chemiluminescence. By combining the use of silver nanoparticles to plasmon enhance chemiluminescence with the use of low power microwaves to localize heating around the nanostructures, we can both optically amplify...

Luminol-mediated chemiluminescence in neutrophils is stimulated by Sendai virus and by influenza virus; Lettré cells also exhibit chemiluminescence (less than 10% of that of neutrophils), which is stimulated by Sendai virus and by influenza virus. Virally induced permeability changes are not responsible for chemiluminescence, since (i) extracellular Ca2+ inhibits permeability changes but stimul...

been aggressively studied based on the concept of the micro total analysis system (µ-TAS). It is called microchip CE. Laser-induced fluorescence (LIF) has been most commonly used as a sensitive detection method in microchip CE. 1 However, LIF detection necessitates a laser light source or spectroscopes. An alternative sensitive detection scheme involves the use of chemiluminescence (CL). Becaus...

a chemiluminescence (cl) method has been developed for the determination of hydroxyzine (hyd) and its metabolite cetirizine (cet). the method is based on sensitizing effect of cet and hyd on the weak cl reaction between ru(phen)32+ and acidic ce(iv). a mechanism for the cl reaction has been proposed on the basis of uv-vis, fluorescent and cl spectra. by using the recommended procedure, the cali...

In the present work, two aptamer-based probes and related sensor systems were developed with chemiluminescence signaling. The detection was based on "turning-on" chemiluminescence with switching "off" of the resonance energy transfer after the aptamer's recognition of the target molecule. In this design, a DNA/aptamer duplex linked a chemiluminescence group and a gold nanoparticle together. ...

The chemiluminescence of gallic acid by hydrogen peroxide had completely inhibited by the presence of ascorbate. After ascorbate had disappeared by oxidation, chemiluminescence returned. The concentration of gallic acid was virtually unchanged by presence of ascorbate, but started to decrease after the disappearance of ascorbate. This might be attributable to the rapid reduction of quinone, whi...

Chemiluminescence probes are considered to be among the most sensitive diagnostic tools that provide high signal-to-noise ratio for various applications such as DNA detection and immunoassays. We have developed a new molecular methodology to design and foresee light-emission properties of turn-ON chemiluminescence dioxetane probes suitable for use under physiological conditions. The methodology...

A sensitive and selective chemiluminescence assay for the determination of quinones was developed. The method was based on generation of reactive oxygen species through the redox reaction between quinone and dithiothreitol as reductant, and then the generated reactive oxygen was detected by luminol chemiluminescence. The chemiluminescence was intense, long-lived, and proportional to quinone con...
