“…30 Poly(ether imide) (PEI), which is rich in tertiary amine groups, is a highly reactive and biocompatible polymer. 31 Although the role of PEI has been reported in self-enhanced ECL systems, 32 their contribution to traditional luminophore/TPrA systems has been neglected and rarely reported so far.…”

The establishment of rapid target identification and analysis methods for antibiotic resistance genes (ARGs) is urgently needed. In this study, we unprecedently designed a target-catalyzed hairpin assembly (CHA) electrochemiluminescent (ECL) biosensor for the ultrasensitive detection of ampicillin resistance genes (ARG AMP ) based on a novel, efficient near-infrared ruthenium carbene complex/TPrA/PEI ternary ECL system with low oxidation potential. The ternary NIR-ECL system illustrated in this work displayed double ECL intensity in comparison with their corresponding traditional binary ECL system. The as-prepared ECL biosensor illustrated in this work demonstrates highly selective and sensitive determination of ARG AMP from 1 fM to 1 nM and a low detection limit of 0.23 fM. Importantly, it also exhibits good accuracy and stabilities to identify ARG AMP in plasmid and bacterial genome DNA, which demonstrates its excellent reliability and great potential in detecting ARG AMP in real environmental samples.
