ABSTRACT:
The present invention generally provides methods and systems for monitoring and controlling electroosmotic flow rates in microfluidic systems. Generally, such methods and systems monitor flow rates in electroosmotically driven microfluidic systems by flowing signaling elements within these channels and measuring the flow rate of these signals. The methods of monitoring flow rates are also applied to methods and systems for continuously monitoring and controlling these flow rates in electroosmotically driven microfluidic systems.
