Abstract
A microfluidic valve for controlling the flow of a material through a microfluidic channel comprising:a) a microfluidic channel comprising a passageway,b) a heater in contact with at least a portion of the microfluidic channel,c) a carrier fluid comprising the material and an amount of thermally-responsive material so that the carrier fluid can be thickened by heat from the heater to cause a reduction in flow of the carrier fluid through the microfluidic channel.
