Detection of epinephrine using a KFeO modified glassy carbon electrode
Iron-based electrochemical catalysts used to modify electrodes for biosensing have received more attention from biosensor manufacturers because of their excellent biocompatibility and low cost. In this work, a fast-ion conductor potassium ferrite (K 2 Fe 4 O 7 ) modified glassy carbon electrode (GCE...
