Quantum Nuts: Two Shells Are Better than One to AchieveHighly Efficient Electrochemiluminescence

摘要

Developingbright and multicolorelectrochemiluminescence (ECL) nanoemitters is widely pursued to achievehigh sensitivity and multiplexing in bioassays and microscopy operatingin physiological conditions. It is a particularly challenging taskconsidering the specific requirements of charge injections and surfacetraps occurring in water during the ECL process. In this issue of , Su, Peng, and co-workers rationalizethe criteria of colloidal quantum dot (QD) architecture for ECL generation. In this exciting report, they present elegantlydesigned water-soluble QDs with an impressive ECL efficiency.
