Bipolar Interdigitated Electrodes for Cell Capture
In this work we focus on using bipolar interdigitated electrodes (BP-IDEs) in a microfluidic device for performing electrochemical analysis of a cluster of cells of defined number and type. A bipolar electrode means that the voltage is not applied directly to the metal film. Instead, current is transferred through an ionic solution. Interdigitated electrodes are a type of bipolar electrode shaped like two forks opposing each other that are not touching. This design allows redox cycling that can be used for biosensing. Initial results have shown the BP-IDEs are equally and individually addressable. Cells are captured on the interdigitated portion of the electrode.
