Abstract
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.
