Abstract
A micro fluidic apparatus includes (i) a first conduit; (ii) a second conduit; and (iii) a first interconnected microporous network in communication with the first and second conduits and configured to allow diffusion of gas between the first and second conduits. The microporous network comprises poly(dimethylsiloxane) (PDMS) and prevents flow of aqueous fluid between the first and second conduits through the microporous network.

A micro fluidic device comprising:
- a first conduit;
- a second conduit;
- and
- a first interconnected microporous network in communication with the first and second conduits and configured to allow diffusion of gas between the first and second conduits,
- wherein the microporous network comprises poly(dimethylsiloxane) (PDMS) and prevents flow of aqueous fluid between the first and second conduits through the porous network.
A method for manufacturing a micro fluidic device comprising:
- disposing a composition in a mold, the composition comprising a PDMS prepolymer and a porogen, the mold configured to form a first part of the microfluidic device, the part having first and second channels;
- curing the composition in the mold to form the first part, wherein the material forming the first part comprises a PDMS polymer interspersed with the porogen;
- removing the porogen from the PDMS polymer to generate a porous first part comprising a microporous PDMS polymer;
- and
- sealing the porous first part to a second part such that a surface of the second part and the first and second channels of the first part together form first and second conduits of the microfluidic device.
