Title:
METHOD AND SYSTEM FOR FLUID CONTROL IN MICROFLUIDIC DEVICE
Document Type and Number:
Japanese Patent JP2012149773
Kind Code:
A
Abstract:
To provide a valve for use in a microfluidic system.
A valve 50 includes a substrate defining an upstream channel 52 and a downstream channel 54 joined by a conduit defined by a first opposed wall 74 disposed at an angle to the central axis 60 of the upstream channel 52. At least a portion of a thermally responsive substance 56 obstructs the conduit by abutment with the first opposed wall 74. Upon actuation of a heat source 37, in thermal contact with the thermally responsive substance 56, an opening motion of the thermally responsive substance 56 opens the conduit.
