Abstract:
1. A microfluidic device, comprising: a first layer of a single type of gas permeable material that defines therein at least two chambers configured for gas flow and at least two chambers configured for liquid flow, wherein the at least two chambers configured for liquid flow are configured differently than the at least two chambers configured for gas flow and the thickness of the gas permeable material separating a chamber configured for gas flow from an adjacent chamber configured for liquid flow is about 1 μm to about 100 μm; and a second layer of the gas permeable material, stacked upon the first layer, defining therein at least two chambers for gas flow and at least two chambers for liquid flow, wherein at least one chamber configured for liquid flow in the first layer is (i) adjacent to and in-plane with at least one chamber configured for gas flow in the first layer and (ii) aligned, in a plane perpendicular to the first layer, with a chamber configured for gas flow in the second layer.
