High-performance electrochemiluminescence is a significant approach for the examination of disease biomarkers, and utilization innovative detection systems represents viable strategy to enhance efficacy ECL analysis. In this work, biomimetic engineering metal-organic framework (MOF-818) has realized ultrasensitive immunoassay markers based on guidance free radical scavenging provided by antioxidant cascade. Initially, we synthesized hydrogen-bonded organic (HOF) consisting luminol three active ligands simple room-temperature self-assembly. The luminol-HOF (L-HOF) showed more stable brighter luminescence activity than monomer due nano-confinement enhancement coordinated units. Subsequently, MOF-818 with superoxide dismutase (SOD) catalase (CAT) activities were recruited first time as quenching agents sandwich mode. enzyme leads reverse transformation anion radicals (O2-) further decomposition, decreasing in responsiveness signals. Using carcinoembryonic antigen (CEA) an analytical model, limit 0.457 pg/mL was obtained within range 0.001-50 ng/mL. We believe that novel sensing model provides meaningful potential tool precise detection, expanding broader application nanoenzymes
