Abstract

original image

Mehr Licht! Die Elektrochemilumineszenz(ECL)-Intensität des Systems [Ru(bpy)3]2+/2-(Dibutylamino)ethanol (DBAE) ist an Au- und Pt-Elektroden 10- bzw. 100-mal so hoch wie diejenige des üblichen Systems [Ru(bpy)3]2+/Tripropylamin (TPA) (siehe Bild). DBAE ist daher ein vielversprechender Zusatzstoff für ECL-Immunassays und DNA-Sondenassays mit [Ru(bpy)3]2+.
