Prudently designed Se@fMWCNT as a peroxidase mimicking nanozyme for distinctive electrochemical detection of H2O2 and glutathione

A Se@fMWCNT nanocomposite with peroxidase mimicking activity was used for the electrochemical detection of H 2 O 2 and glutathione. Both analytes were detected using amperometry at a low potential of −0.2 V, with excellent selectivity and sensitivity.
