Abstract

A method of operating a microfluidic device (15) wherein the microfluidic device comprises a microfluidic channel (20) a fluid conveyance extension (30) and an absorbent microfluidic flow modulator (35). The microfluidic channel extends from a channel outlet chamber (25) of the microfluidic device and the fluid conveyance extension is fluidly coupled to the channel outlet chamber. The absorbent microfluidic flow modulator is configured to absorb a fluid from the fluid conveyance extension when fluidly coupled to the fluid conveyance extension. The method comprises admitting the fluid into the microfluidic channel and the channel outlet chamber saturating the fluid conveyance extension with the fluid and generating a fluid flow in the microfluidic channel by fluidly coupling the absorbent microfluidic flow modulator to the fluid conveyance extension to absorb the fluid from the fluid conveyance extension.
