A method for fabricating microfluidic electrochemical reactors

We report an efficient method for the fabrication of microfluidic electrochemical reactors. The technique relies on soft lithography and micromolding in capillaries. Intrinsic to our method of fabrication is the capability of controlling the inter-electrode gap between 40 to 200 microm, and the ability to produce microchannels with complex geometries. The material selected to fabricate the reactor is resistant to most organic solvents, whereas its relative softness eliminates the need for additional sealants required by other methods for the fabrication of microfluidic electrochemical reactors.
