The present study describes the synthesis of well aligned and highly dense polyethylene glycol template assisted cupric oxide (CuO) nanoleaves on the gold coated glass substrate by hydrothermal growth method. The structural study based investigations of CuO nanoleaves were performed by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX), infrared reflection-absorption spectroscopy (IRAS), and high resolution transmission electron microscopy (HRTEM). The glucose sensor based on the glucose oxidase immobilized CuO nanoleaves electrode detected the wide range of glucose concentrations with good linearity and exhibited high sensitivity of 61.9 {+-} 2.0 mV/decade. The linear detection range was observed from 1.0 Multiplication-Sign 10{sup -5} to 2.0 Multiplication-Sign 10{sup -2} M with detection limit of 5.0 Multiplication-Sign 10{sup -6} M and a fast response time of less than 5 s was also observed. The glucose sensor electrode possesses good anti-interference ability, stability, repeatability, and reproducibility.
