A microfluidic rotary valve and methods of manufacturing same are disclosed. The rotary valve includes a stator chip having at least one inlet and at least one outlet. The rotary valve also includes a rotor having at least one rotor channel in sealed engagement with the stator chip. The rotor rotates between valve positions preventing and allowing fluid communication between the inlets and outlets by way of the rotor channels and according to the design of the inlets, outlets and rotor channels. The stator chip includes a first planar substrate having a contact face and a second planar substrate having a contact face bonded to the contact face of the first planar substrate. The first planar substrate defines a first portion of the inlet and outlet, and the second planar substrate defines a second portion of the inlet and outlet.

Microfluidic valve and method of manufacturing same

A method of controlling flow of a driven fluid in a channel, the channel being defined by an encircling wall, the method comprising the steps of sealing the channel with a sealing fluid immiscible in the driven fluid blocking the channel at an initial position, in which the sealing fluid has a first contact angle with the encircling wall and the driven fluid has a second contact angle with the encircling wall and the first contact angle is less than the second contact angle; and moving the sealing fluid in the channel by a force generated outside of the channel. Apparatus for controlling flow of a driven fluid in a channel, the apparatus comprising, an encircling wall defining a channel, a sealing fluid in the channel, the sealing fluid having a first contact angle with the encircling wall, a driven fluid in the channel having an interface with the sealing fluid, the driven fluid having a second contact angle with the encircling wall, the first contact angle being less than the second contact angle; and a force generator exterior to the channel, the force generator being operable to move the sealing fluid within the channel.
