In this work, curcumin-Ni complex was prepared via a simple electrodeposition and applied for Amyloid beta (Aβ) detection. The morphology, chemical composition and electrochemical properties of the complex were confirmed by scanning electron microscopy, Fourier transform infrared spectroscopy and cyclic voltammetry, respectively. The complex interacted specially with Aβ. The surface resistance-change of the complex electrode was confirmed by electrochemical impedance spectroscopy in the presence of Aβ. The resistance was increased with the increase of Aβ concentration. The curcumin-Ni complex electrode showed low detection limits as well as linear range response. Hence, the curcumin-Ni complex electrode is a promising candidate for effective electrochemical Aβ sensor. |
