摘要：Electrochemiluminescence (ECL), also referred to as electrogenerated chemiluminescence, is chemiluminescence triggered by electrochemical processes. The combination of chemiluminescence and electrochemistry brings ECL many unique advantages such as rapidity, high sensitivity, and simplified optical setup. As an analytical technique, ECL does not require the use of any external light source. Thus, the attendant problems of scattered light and luminescent impurities are absent, which leads to low optical background noise and high sensitivity for analysis. Fundamentally, the ECL properties and biosensing strategies of QDs should have many relations to the PL of QDs. It was noticed that ECL from QDs in light of their PL properties and PL-based sensing strategies may provide much better understanding of the ECL. However, the critical relationship and difference between ECL and PL of QDs and also the similarities and differences of ECL biosensing schemes as compared to PL sensing strategies still remains unsummarized.
