The PCB electrodes are equipped with a proprietary coating technology to enable the use of printed circuit boards for developing electrochemical applications without interference from copper base metal.
PCB electrodes are suitable for working with microvolume sample droplets as well as by dipping into the target solution. They are an ideal platform to develop biosensors and chemosensors at the point of need.
Thanks to the gold surface, the electrodes can be readily functionalized with thiol-based ligands to develop electrochemical molecular diagnostics, immunosensors, ISE and more.
These electrodes are recommended for use in the -1.5 to +0.8 V vs Ag/AgCl range in chloride-based electrolytes such as phosphate buffered saline (PBS) for continuous cycling and from -1.5 to +1 V vs Ag/AgCl for just a few measurements.
Rinsing in DI water and N2 drying is normally sufficient cleaning for most applications. For more aggressive electrochemical cleaning: perform cyclic voltammetry in the range of -1 to +1.25 V vs Ag/AgCl using 0.1 M H2SO4.
