    A CoFe Prussian blue analogue (CoFe PB) modified FTO electrode, prepared via a facile electrodepositionmethod, is investigated as a non-enzymatic glucose sensor under neutral conditions. The electrode ex-hibits a linear detection of glucose in the 0.1e8.2 mmol/L range with a detection limit of 67mM, asensitivity of 18.69mA/mM.cm2, and a fast response time of less than 7 s under neutral conditions. Its stability is confirmed with both electrochemical experiments and characterization studies performed on the pristine and post-mortem electrode. We also conducted a comprehensive electrochemical analysis to elucidate the identity of the active site and the glucose oxidation mechanism on the Prussian blue surface.
