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

Abstract

Here, the nanocomposite of Cu2+-PEI-Pt/AuNCs with multipath signal catalytic amplification to peroxydisulfate-dissolved oxygen electrochemiluminescence (ECL) system was prepared to fabricate sensitive ECL immunosensor. Using polyethyleneimine (PEI), a linear polymer, as...
