  • Microfluidic, electrochemical devices
    Patent number: 9192933
    Abstract: Microfluidic, electrochemical devices are described. The microfluidic, electrochemical device comprises one or more electrode(s) on a substrate and a patterned porous, hydrophilic layer having a fluid-impermeable barrier which substantially permeates the thickness of the porous, hydrophilic layer and defines boundaries of one or more hydrophilic channels within the patterned porous, hydrophilic layer, wherein the hydrophilic channel(s) comprises a hydrophilic region which is in fluidic communication with the electrode(s). In some embodiments, the electrodes comprise a working electrode, a counter electrode, and a reference electrode. In some embodiments, the microfluidic, electrochemical device further comprises a fluid sink. The method of assembling the microfluidic, electrochemical device is described. The method of using the device for electrochemical analysis of one or more analytes is also described.
