A more universal Co2+/ABEI-AuNFs-cDNA complex that can significantly enhance the CL intensity was synthesized with easier operation. Fe3O4 MNPs based solid-phase RCA strategy was fabricated and Co2+/ABEI-AuNFs was used as signal probes. A steady-state chemiluminescent aptasensor was fabricated to detect S. typhimurium with high sensitivity and specificity.
