Abstract:

Electrochemiluminescence(ECL) has become one of the most advanced immunodiagnostic method due to its near-zero background and high sensitivity. Ruthenium(Ⅱ) tris(bipyridine)[Ru(bpy)32+] and its derivatives have been applied in commercial diagnostics, but their optical properties can not meet the requirement of state-of-art ECL analysis. Quantum dots(QDs) possess outstanding luminescence properties and seem to be ideal for developing a new generation of ECL emitters. However, the mechanism of ECL generation from QDs deserves further in-depth investigations and the ECL performance of QDs also needs to be improved. In this review, we focus on the important advancements and key scientific issues of QDs ECL. After an overview of the developments of the field, future perspectives about the developments of QDs ECL are also exhibited. We believe that spectroscopy, synthesis chemistry and electrochemistry should be combined together to advance the research.
