US Patent 7201833 Integrated solid-phase hydrophilic matrix circuits and micro-arrays

The invention is directed to analytical devices and micro-arrays with integral fluidic inputs and outputs. The devices are constructed from planar solid-phase hydrophilic matrix circuits containing dry chemical reagents overlaying integral electro-kinetic pumping electrodes. The hydrophilic matrix circuits are enclosed within a gas permeable electrical insulator. The devices are for use in micro-scale bio-analysis, mixture separation and reaction.
