| Research Abstract |
In this study, we have proposed a novel method for electrochemical imaging using local redox cycling-based electrochemical (LRC-EC) devices and systems. In the device, two arrays of microelectrodes are orthogonally arranged to fabricate an n × n array of crossing points (measurement points) with only 2n bonding pads for external connection. The crossing points of the column and row electrodes can easily be addressed by setting the proper potentials at the column and row electrodes to induce local redox cycling at desired crossing points. Therefore, the crossing points can be used as individual electrochemical sensors. This addressable and multiple detection system successfully applied for the detection of enzyme activity, gene-expression analysis, cell differentiation analysis, DNA detection and dynamic analyses of droplets. The present LRC-EC system will be widely applicable for various bioimaging and biosensing.
