A ferrocenyl-terminated dendrimer as an efficient quencher via electron and energy transfer for cathodic electrochemiluminescent bioanalysis.

A novel ferrocenyl-terminated dendrimer with an electron-relay framework was designed as an efficient tracing tag to quench the cathodic electrochemiluminescence emission of quantum dots, which led to a dual quenching effect via both electron and energy transfer for construction of a sensitive bioanalysis strategy.
