Wearable Noninvasive Glucose Sensor Based on Cu_xO NFs/Cu NPs Nanocomposites.

ABSTRACT: Designing highly active material to fabricate a high-performance noninvasive wearable glucose sensor was of great importance for diabetes monitoring. In this work, we developed Cu_xO nanoflakes (NFs)/Cu nanoparticles (NPs) nanocomposites to serve as the sensing materials for noninvasive sweat-based wearable glucose sensors. We involve CuCl₂ to enhance the oxidation of Cu NPs to generate Cu₂O/CuO NFs on the surface. Due to more active sites endowed by the Cu_xO NFs, the as-prepared sample exhibited high sensitivity (779 μA mM^-1 cm^-2) for noninvasive wearable sweat sensing. Combined with a low detection limit (79.1 nM), high selectivity and the durability of bending and twisting, the Cu_xO NFs/Cu NPs-based sensor can d
