High surface area mesoporous CuO: a high-performance electrocatalyst for non-enzymatic glucose biosensing

A highly sensitive and selective non-enzymatic glucose biosensor has been successfully constructed using high surface area mesoporous CuO (108 m(2) g(-1)) templated by mesoporous carbon. The glucose biosensor exhibits a low detection limit of 0.23 mu M at a signal-to-noise ratio of 3.
