    Abstract: A fluid gating valve includes a porous hydrophobic layer which acts a barrier for liquid flow; a liquid source on one side of the porous layer; a liquid drain on the opposing side of the porous hydrophobic layer; a source electrode in electrical connection with the liquid source; and a gate electrode electrically insulated from the liquid source, wherein the source electrode and the gate electrode are positioned and arranged to be connectable to a voltage source. And valve can be open by applying voltage between the gate and the source electrodes.

    Abstract: According to the invention there is a microfluidic chip (1) that includes at least two layers (10) forming a stack of layers, each layer of which has at least one flow channel (14); a bore (16) extending through the layers and communicating with a plurality of flow channels; and a valve (20), which has a shaft (22) with a recess (222) in a side of the shaft for fluid to flow through. The shaft is rotatably mounted in the bore, and has a first position in which the recess is aligned with each of at least two flow channels of the plurality of flow channels thereby providing a flow path between said at least two flow channels, and a second position in which the recess is unaligned with at least one of said at least two flow channels the flow path between said at least two flow channels thereby being closed. This allows a fluid flow path between two flow channels to be open and closed by rotation of the shaft so that fluid in the microfluidic chip can be redirected to allow the chip to have greater capability and by using a minimal amount of space on the chip to do so.

    Abstract: The present invention relates to a fluid triggerable passive valve for controlling flow of one or more fluids comprising: a volume comprising at least two capillary pressure barriers for respectively pinning a first and second fluid-fluid meniscus, the two capillary pressure barriers dividing the volume in at least three sub volumes, whereby two sub volumes being positioned upstream and one sub volume being positioned downstream with respect to the advancement direction of each respective fluid-fluid meniscus; wherein the capillary pressure barriers are spaced apart such that upon pinning of a first fluid-fluid meniscus on a first capillary pressure barrier and arrival or pinning of a second fluid-fluid meniscus on or at a second capillary pressure barrier, the two menisci touch and thereby coalesce into one fluid-fluid meniscus
