A Novel Non-enzymatic Glucose Sensor Based on Ag Nanoparticles Electrodeposited on Polyaniline Films

Author(s): Xu Chun Song, Ling Wang, Hao Yong Yin.

Abstract:

The Ag/polyaniline (Ag/PANI) films have been prepared by a two-step electrochemical method. The PANI film was firstly grown by a potentiodynamic polymerization method in aniline electrolytes, and then Ag nanoparticles were electrodeposited on the PANI film through potentiostatic methods in 0.1 M AgNO3 solution. The products were characterized in detail by multiform techniques: X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDS), scanning electron microscopy (SEM). The obtained Ag/PANI electrode was used as glucose sensor to detect glucose in 0.1 mol/L KOH. The results show excellent electrocatalytic activity for glucose detection on the present electrochemical sensing platform.
