Abstract

In this paper, an electrochemiluminescence resonance energy transfer (ECL-RET) system from CdS quantum dot to Ru(bpy)(3)(2+) was developed for the first time. By the signal amplification of Ru(bpy)(3)(2+) and the specific antibody-cell surface interactions, this ECL-RET system could sensitively respond down to 12.5 SMMC-7721 cells per mL.
