Abstract
Lab-on-Chip is a technology that coul
d potentially revolutionize medical
Point-of-Care diagnostics. Cons
iderable research effort is
focused towards innovating
production technologies that will make commer
cial upscaling financially viable. Printed
circuit board manufacturing techni
ques offer several prospects in
this field. Here, we present
a novel approach to manufacturing Printed Ci
rcuit Board (PCB)-based Ag/AgCl reference
electrodes, an essential com
ponent of biosensors. Our prot
otypes were characterized both
structurally and electri
cally. Scanning Electron Mi
croscopy (SEM) and X-Ray
Photoelectron Spectroscopy (XPS) were empl
oyed to evaluate the electrode surface
characteristics. Electrical characterization was performed to determine stability and pH
dependency. Finally, we demonstrate utilizat
ion along with PCB pH sensors, as a step
towards a fully integrated PCB platform, comp
aring performance with discrete commercial
reference electrodes.
