ResumoWe 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 0.01 μM to 11.0 mM), an ultra-low detection limit (0.035 μM) and a high sensitivity (0.933 mA/mM cm2). Furthermore, the proposed biosensor showed high selectivity and favorable reproducibility along with long-term performance stability.
