Abstract

Lab-on-PCB microsystems present a promising alternative for cost-effective mass production of Lab-on-Chip based Point-of-Care diagnostic devices. In this work we present the first commercially fabricated PCB-based electrochemical glucose biosensor platform. Measurement electrodes (working and counter) were made from gold-plated PCB-vias, with a Ag/AgCl reference electrode integrated in the platform in a double-layer structure. The electrode surfaces are electrochemically pretreated in H2SO4 to improve electrode uniformity and stability, prior to immobilizing glucose oxidase on the working electrode surface via electropolymerization of phenol. Amperometry was employed to measure glucose with a logarithmic response of current against glucose concentration in the 0.01-10mM range.
