▎ 摘　　要

Based on the K-doped graphene-CdS:Eu NC composites and the nicking endonuclease (NEase) assisted strand-scission cycle, we have developed an ultrasensitive and selective electrochemiluminescence (ECL) DNA biosensor using the G-quadruplex-hemin-based DNAzyme which acts as an electrocatalyst for the reduction of H2O2, the coreactant of CdS:Eu NCs ECL.
