Abstract
An electronic device performs active biological operations such as, for example, the analysis of a solution containing charged biological materials. The device can take the form of a flow cell that includes an inlet chamber and an outlet chamber connected to a flow cell chamber. An array containing a plurality of electrodes is contained within the flow cell chamber. Inlet and outlet ports are provided in the inlet chamber and outlet chamber, respectively. The inlet and outlet chambers advantageously have substantially constant cross-sectional flow areas.
