"Double-featured Chemiluminescence Reagent Prepared Through A Mixing Procedure And Its Application To The Detection Of Heme Protein"
Anal. Sci. 2000 Volume 16, Issue 12 Pages 1357-1359

Abstract: In this paper, we propose a double-featured CL reagent prepared through a mixing procedure in order to expand the use of the conventional CL reagents. As a first attempt, both luminol and TCPO were dissolved in methanol together with H2O2 to prepare a double-featured CL reagent solution. A unique performance was demonstrated as an initial result, which has never been observed in an individual CL reagent. The FIA system using the double-featured CL reagent solution could detect both a metal complex and a fluorescence compound. The system was also applied to the detection of a dyestuff-labeled heme protein. Although the analytical conditions must be examined in more detail, the data given here should provide a clue for thinking about new uses and applications of the CL reaction.

"Chemiluminescence Property Of The Luminol-hydrogen Peroxide-copper(II) System In The Presence Of Surface-carboxylated Microspheres"
Anal. Sci. 1998 Volume 14, Issue 2 Pages 409-412

Abstract: The cathodoluminescence was studied of a luminol-hydrogen peroxide-copper(II) system in the presence of surface-carboxylated microspheres. The results should provide important information not only concerning anal. applications of the cathodoluminescence reaction in an emulsion, but also to a specific liq.-solid interface chemical using microspheres as functional materials.

"High-sensitivity Determination Of Emetine Dithiocarbamate Copper(ii) Complex Using The Electrogenerated Chemiluminescence Detection Of Tris(2,2'-bipyridine)ruthenium(ii)"

Abstract: The emetine dithiocarbamate Cu(II) complex (I) was used in an FIA system equipped with an electrogenerated chemiluminescence (CL) detector (schematic given). The carrier was 10 mM phosphate buffer of pH 4 containing 35% acetonitrile and the CL reagent was 10 mM Ru(bpy)32+ in H2SO4). All tubes were of Teflon. The detection cell was a 500 m i.d. Teflon tube covered with black Tygon tape, but with an 11 mm detection window in front of the photomultiplier tube. Capillary electrophoresis was performed in a fused-silica capillary (50 cm x 50 mm i.d.), migration buffer was 25 mM phosphate buffer (pH 3.5) containing 35% acetonitrile, and applied voltage was 20 kV. The calibration graph was linear from 1-10 M I with a detection limit of 0.1 nM Cu(II) (65 fg).
