Various textile-based composite conductive materials have been extensively applied for wearable and flexible electronics recently owing to their high flexibility and bio-friendliness. Among these textile-based electronics, flexible non-enzymatic glucose sensors have especially attracted attention because they can diagnose human health status by monitoring glucose concentrations in human sweat, tears, and blood. In this paper, reduced graphene oxide (RGO) was in situ synthesized on cotton fabric (CF) by a hydrothermal reduction method to prepare reduced graphene oxide cotton fabrics (RGO/CF). Copper nanowires (CuNWs) were deposited on reduced graphene oxide cotton fabrics by vacuum filtration to obtain copper nanowires/reduced graphene oxide cotton fabrics (CuNW/RGO/CF) and applied to non-enzymatic glucose biosensing. Under the optimized conditions, the CuNW/RGO/CF sensor exhibits excellent catalytic performance for glucose oxidation and a series of excellent properties, such as the rapid response time and high sensitivity at 1020 mu A mM(-1) cm(-2). Glucose concentrations in human sweat, serum and juice were analyzed by amperometric method, and the recoveries ranged from 97.00 to 109.00% (RSD
