Fabricating electrodes for amperometric detection in hybrid paper/polymer lab-on-a-chip devices

Journal Article


Abstract


  • We present a novel, low-resource fabrication and assembly method for creating disposable

    amperometric detectors in hybrid paper–polymer devices. Currently, mere paper-based microfluidics

    is far from being able to achieve the same level of process control and integration as state-of-the-art

    microfluidic devices made of polymers. To overcome this limitation, in this work both substrate types

    are synergistically combined through a hybrid, multi-component/multi-material system assembly.

    Using established inkjet wax printing, we transform the paper into a profoundly hydrophobic

    substrate in order to create carbon electrodes which are simply patterned from carbon inks via custom

    made adhesive stencils. By virtue of the compressibility of the paper substrate, the resulting electrodeon-

    paper hybrids can be directly embedded in conventional, 3D polymeric devices by bonding

    through an adhesive layer. This manufacturing scheme can be easily recreated with readily available

    off-the-shelf equipment, and is extremely cost-efficient and rapid with turn-around times of only a few

    hours.
