“…Studies have shown that nanomaterials, particularly metal nanomaterials, 19 can considerably enhance the ECL of luminol. 20 Bimetallic nanomaterials, consisting of two different metals in various forms and structures such as alloys, core− shell structures, subclusters, and intermetallic forms, have been prepared, exhibiting excellent catalytic performance, high electrical conductivity, and commendable biocompatibility. 21 Bimetallic nanoparticles (NPs) offer several advantages over single metal NPs: cost reduction by introducing economical materials such as Fe, Cu, or Ni; the ability to regulate properties through composition and morphology adjustments for optimal performance and atomic utilization; enhanced catalytic activity attributed to the synergistic effect between two metals.…”
