Abstract

We demonstrate the fabrication and characterization of a flexible non-enzymatic electrochemical glucose sensor whose sensing electrode consists of electroplated Cu nanoparticles(NPs) on the laser-induced-graphene fiber (LIGF) and laser-induced porous graphene (LIG) double layer, which was made on a PI film. The non-enzymatic electrochemical glucose sensor with Cu-NPs/LIGF/LIG sensing electrode shows excellent glucose detection characteristics, including a sensitivity of 1438.8A μ/mMcm2, limit of detection (LOD) of 124 nM, and broad linear range at an applied potential of +600mV.

IV. CONCLUSIONS The proposed non-enzymatic electrochemical glucose sensor with Cu-NPs/LIGF/LIG sensing electrode was successfully fabricated and characterized. The glucose sensor fabricated by a conventional Cu electroplating shows excellent detection result such as high sensitivity of 1438.8 μA/mM·cm2, low detection limit of 124 nM, and a broad linear range at an applied potential of +600 mV. This type of the sensor offers an inexpensive, facile method to fabricate nonenzymatic glucose sensors.
