Abstract

The invention discloses a metal nanoparticles/nanocellulose composites-based non-enzymatic electrochemical glucose sensor, comprising a three-electrode system composed of a working electrode, a counter electrode, and a reference electrode. The surface of the working electrode is coated with a metal nanoparticles/nanocellulose composites. The surface of the nanocellulose is modified with a strong cationic conducting polymer. The invention promotes the sensitivity and selectivity of glucose sensing with the linear range of 4 μM-15 mM and the detection limit of 1.4 μM. Therefore, the sensor possesses high sensitivity, high response speed, stable performance and high anti-interference ability. The preparation method of the metal nanoparticles/nanocellulose composites-based non-enzymatic electrochemical glucose sensor is simple and the cost is low. And enzyme is introduced into the preparation process.
