Macias Sensors’ PCB electrodes are equipped with our proprietary coating technology to enable the use of printed circuit boards for developing electrochemical applications without interference from copper base metal.
These PCB electrodes are suitable for working with microvolume sample droplets as well as by dipping into the target solution. Thus, they are an ideal platform to develop biosensors and chemosensors to be used at the point of need. The wide electrochemical stability window (-1.5 to +1 V vs Ag/AgCl in PBS pH 7.4) allows for many different experiments.
Furthermore, thanks to the gold surface, the electrodes can be readily functionalized with thiol-based ligands to develop electrochemical molecular diagnostics, immunosensors, ISE and more.
The electrodes are delivered in boxes of 10 pieces.
Rinsing in DI water and N2 drying is normally sufficient cleaning for most applications. But if you would like to use a harsher electrochemical cleaning, we recommend performing cyclic voltammetry in the range of -1 to +1.25 V vs Ag/AgCl using 0.1 M H2SO4.
