Microwave Synthesized CuO Nanoleaves as Nonenzymatic Glucose Sensor

Abstract:

CuO nanoleaves have been synthesized by cetyl trimethyl ammonium bromide (CTAB)-assisted microwave method and characterized by powder X-ray and selected area electron diffractions, scanning and transmission electron microscopies and energy dispersive X-ray and electrochemical impedance spectroscopies. The CuO nanoleaves on graphite nonenzymatically sense glucose electrochemically. Cyclic voltammetic and chronoamperometric studies reveal the excellent catalytic activity of the modified electrode towards direct glucose oxidation. A wider linear range of glucose concentration and a shorter response time are observed. The detection limit of glucose is as low as 4µM and the CuO nanoleaves can be used as efficient electrochemical sensor.
