Thispaper develops an efficient electrochemiluminescence (ECL)enhancement strategy on closed bipolar electrode for the detectionof prostate specific antigen (PSA). We first synthesized a cyclometalatediridium(III) complex (pq) 2Irbza with high ECL efficiencyand used as ECL emitter in the anodic cell of BPE. While we introduceda Pt-tipped Au NRs and constructed a sandwich immune structure atthe cathodic pole of BPE. Combined the signal amplification strategiesof enzyme catalysis and the synergistic catalytic effect of bimetallicstructure for the reduction of H 2O 2, the attachedPt-tipped Au NRs-GOx-Ab 2 nanocomplex as both recognitionprobes and signal amplification units could mediate the ECL signalsof (pq) 2Irbza/tripropylamine (TPrA) on the anodes of BPEthrough faradaic reaction due to the charge neutrality of BPE. Therefore,a highly sensitive BPE-ECL sensor for detection of PSA with a detectionlimit of 0.72 pg/mL and a linear range from 1.0 pg/mL to 10 ng/mLwas obtained.

This work is expected to broaden the application ofiridium complex and bimetallic nanocatalyst in biological detectionand could be utilized to detect many other biological molecules.
