Abstract
The present invention relates generally to the control of fluid flow rate and direction on a microfluidic device. In particular, the present invention provides an integrated valveless microfluidic device, where directional fluid control is controlled using off-chip remote valve switching and fluid flow rate changes are controlled using on-chip flow-rate changing fluid reservoirs. The present invention provides methods and systems for directional fluid control and control of fluid flow rate in an integrated microfluidic device which enables processes with different flow rates to be performed on one device without the need of on-chip valves.
