摘要：
We present a new strategy for the fabrication of a fully integrated electrochemical platform. The three-electrode system consists of an indium tin oxide interdigitated array as working electrode, a solid-state reference electrode, and an electrodeposited Pt counter electrode that are placed in microfluidic channel. By controlling the electrodeposition conditions, such as the applied potential and time, the stability and uniformity of the films can be optimized. A solid-state reference electrode was fabricated on the nanoporous Pt via electropolymerization of poly-1,3-phenylenediamine. This system provides a simple method for the fabrication of three-electrode system and opens the possibility for an electroanalytical platform.
