Glucose-assisted synthesis of Cu 2 O shuriken-like nanostructures and their application as nonenzymatic glucose biosensors

We have successfully synthesized high quality cuprous oxide shuriken-like nanostructures by low temperature hydrothermal process, using glucose as reducing agent. The resulting nanostructures were further characterized for the fabrication of nonenzymatic glucose biosensors. The glucose sensors exhibited excellent performances, giving a wide linear detection range (from 0.01μM to 11.0mM), an ultra-low detection limit (0.035μM) and a high sensitivity (0.933mA/mMcm2). Furthermore, the proposed biosensor showed high selectivity and favorable reproducibility along with long-term performance stability.
