Addressable Electrode Array Device Incorporated with Ida Electrodes for Biological Analyses

In the past decade, several kinds of microelectrode arrays have been applied to chemical and biological analyses. These electrochemical array devices have substantial advantages, including rapid response time and qualitative and quantitative detection. Among the various systems that are based on electrochemical detection, individually addressable electrode arrays have been used for simultaneous multi-analyte detection. In many cases, the multianalyte detection was realized using individual addressing by connecting each electrode to a corresponding bond pad in the 1:1 mode. Therefore, the integration of a large number of electrodes is difficult because the space for bond pads on the chip border is limited.
