Novel application of CoFe layered double hydroxide nanoplates for colorimetric detection of H2O2 and glucose

The present communication demonstrates the proof of concept of using CoFe layered double hydroxide (CoFe-LDHs) nanoplates as an effective peroxidase mimetic to catalyze the oxidation of peroxidase substrate 3,3′,5,5′-tetramethylbenzidine in the presence of H2O2 to produce a blue solution. We further demonstrate successfully CoFe-LDHs nanoplate-based colorimetric assay to detect H2O2 and glucose.
