摘　　要：利用电沉积法在ITO电极表面修饰了一薄层NiOx,通过循环伏安和计时电流等方法研究了该修饰电极的电化学特性。实验表明：该修饰电极对葡萄糖有良好的催化作用,对葡萄糖检测的线性范围为0.001～1.0 mmol/L,检出限为0.3μmol/L（S/N=3）,灵敏度为65.26μA·（mmol/L）^-1,响应时间为3 s。传感器可用于实际样品的测定。A thin film of nanonickel oxide nanoparticle modified electrode on the surface of ITO has been fabricated by electrodeposition.The cyclic voltammetric（CV） and chronoamperometric characterizations reveal that the modified electrode exhibits an excellent electrocatalytic activity,a wide linear range for glucose concentration from 1.0 μmol/L to 1.0 mmol/L with a detection limit of 0.3 μmol/L（S/N = 3） and a response time of 3 s.The preparation of the sensor is simple and has good reproducibility and stability.It has been applied to analysis of blood serum samples.
