Abstract
A glucose sensor was fabricated by combing the Ni(OH)2 and Au nanoparticles with their own superior characteristics. The structure and morphology of tremella-like Ni(OH)2 and Ni(OH)2/Au nanohybrid film were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and ultraviolet–visible absorption spectrometry (UV–vis). The electrochemical properties of the sensor were explored by cyclic voltammetry and amperometry. The investigation showed that the Ni(OH)2/Au nanohybrid film at the sensor exhibited a high electrocatalytic activity towards electrooxidation of glucose; and under the optimal conditions, the linear ranges of glucose were from 5μM to 2.2mM with a low detection limit of 0.92μM (S/N=3) and high sensitivity of 371.2μAmM−1cm−2. The results demonstrated that Ni(OH)2/Au nanocomposite film was promising to be a new platform for the construction of glucose biosensors.
