Microporous Prussian Blue/gold composite material was prepared with electrochemical deposition and hydrogen bubble as a template. We designeda highly sensitive electrochemical glucose sensor through immobilizing glucose oxidase on the surface of the composite material. We further employed typical current-time response to investigate its electro-catalytic property to glucose. Results show that its response time is 7 s,and linear detection range is 0.05 to 3.75 mmol /L. The sensor also has better reproducibility and higher stability.
