An electrochemiluminescence immunosensor based on multipath signal catalytic amplification integrated in a Cu2+–PEI–Pt/AuNC nanocomposite

In this work, Cu 2+ –PEI–Pt/AuNCs, a chain-like nanocomposite integrated with multipath signal catalytic amplification for the ECL of a peroxydisulfate–dissolved oxygen ECL system, was prepared to fabricate a sensitive ECL immunosensor.
