Abstract

In this work we integrate Electrolyte-Gated Field-Effect transistors (EGFET) in Lab-on-Printed Circuit Board (Lab-on-PCB) microsystems for the first time, aiming for the implementation of an ultra-high sensitivity biosensing platform that can still be cost-effectively mass-produced. Silver-nanoparticle ink was ink-jet printed on PCB-based gold electrodes and was chlorinated to fabricate stable pseudo-reference electrodes. Graphene ink was drop-casted to create the transistor channel. Preliminary results with single-stranded DNA (ssDNA) immobilized on the graphene surface revealed systematic shift in V_dirac with increasing complementary DNA concentration.
