A graphene quantum dots based electrochemiluminescence immunosensor for carcinoembryonic antigen detection using poly(5-formylindole)/reduced graphene oxide nanocomposite

A sandwich-type ECL immunosensor based on P5FIn/erGO nanocomposite was developed for CEA detection using GQDs@AuNP nanocomposite as the ECL probe. This ECL immunosensor had good stability, reproducibility and specificity.285
