Fe–Co bimetallic alloy nanoparticles as a highly active peroxidase mimetic and its application in biosensing

This article presents a new enzyme-mimic activity of non-noble metal-based bimetallic Fe–Co NPs. This type of enzyme-mimic exhibits much higher affinity to H2O2 over other NPs-based peroxidase mimetics by at least one order of magnitude due to the synergistic effects between the two metals.
