N2 - This work proposes an electroplating Ag/AgCl method to modify microelectrode arrays for the application of neural prosthesis. The conventional Ag/AgCl electrode is considered as a reference electrode due to its excellent long-term stability. However, the Ag/AgCl modified microelectrode is chosen as a working electrode in this work. The electrode with the surface area of 3.14 × 10-4 cm2 was fabricated individually by electroplating silver. The surface of the electroplated silver was chemically chloridised to form the Ag/AgCl microelectrode. The experimental results show that the fabricated Ag/AgCl microelectrode exhibits higher charge storage capacity than the unmodified microelectrode. The impedance of the Ag/AgCl modified microelectrode at 0.1 Hz is 7447 O, which decreases with two orders of magnitude compared to the unmodified one. What is more, the Ag/AgCl modified microelectrode shows clearly enhanced transduction in ionic media and improved stability based on impedance spectroscopy results. Therefore, this functionalised Ag/AgCl can be deployed as a significant electrochemical modification material.
