Copper-based materials, renowned for their redox versatility and conductivity, have extensive applications in electrochemical sensing. Herein, we construct stable Cu+/Cu2+ interfaces within dual-valence copper nanostructures to achieve enhanced sensitivity glucose By employing a hydrolysis method tune Cu2+/Cu+ ratios precisely, achieved an optimal interface with heightened stability reactivity. The interface-based flexible electrode demonstrated excellent (332.4 µA mmol/L−1 cm−2 at +0.65 V), wide linear range (up 10 mmol), low detection limit of 1.02 nmol/L, strong selectivity, including human sweat, making this study significant advanced sensors.
