An effective electrochemiluminescence (ECL) sensor was developed by combining bis(2,2′-bipyridine)-5-amino-1,10-phenanthroline ruthenium(II) [Ru(bpy) 2 (5-NH 2 -1,10-phen) 2+ ] with functionalized carbon nanotubes (FCNTs) coated on a glassy carbon electrode. Treatment with a nitric acid and sulfuric acid mixture (1:3, v/v) led to multiwall carbon nanotubes terminated with carboxylic...
Electrogenerated chemiluminescences (ECLs) of quinolizidine alkaloids including matrine (MT), sophocarpine (SC), and sophoridine (SRI) are studied. The light emission is caused by an electro-oxidation reaction between Ru(bpy)32+ and the tertiary amino group on the alkaloid compounds. A thin-layer flow cell equipped with a glassy carbon disk electrode (22.1mm2) at the potential of +1.30V (vs. Ag/AgCl)...
