Abstract:
1. A microfluidic, electrochemical analysis device comprising: plural porous, hydrophilic layers, respectively separated by a fluid impermeable layer defining one or more openings in alignment with at least a portion of one or more hydrophilic channels within a hydrophilic layer to permit vertical fluidic communication through said fluid impermeable layer between said hydrophilic layers, wherein a porous, hydrophilic layer comprises a fluid sample deposition region and a patterned, fluid impermeable boundary that substantially permeates the thickness of the hydrophilic layer and defines the one or more hydrophilic channels therewithin in fluidic communication with said deposition region which permit fluidic flow within the one or more channels; and an electrode assembly comprising one or more electrodes in fluidic communication with said deposition region through the one or more hydrophilic channels, wherein said electrode assembly is disposed in fluidic communication with the one or more hydrophilic channels on one hydrophilic layer and a sample deposition region disposed on another hydrophilic layer.
