Three-Dimensional Copper Foam Supported CuO Nanowire Arrays: An Efficient Non-enzymatic Glucose Sensor

[Display omitted] •The CuO nanowire arrays composite was synthesized on copper foam.•The CuO nanowires were covered by CuO nanoflowers evenly, providing more active sites.•The sensor exhibits excellent sensitivity, selectivity, reproducibility, and stability toward glucose sensing without any polyme...
