This thin-film sensor has a microfluidic channel integrated.
The Micrux Thin-Film electrodes are reusable and need only 1 to 5 µL measuring solution to be operated. The sensors with microfluidic are available with platinum or gold electrode. The WE material is sputtered on a 50 nm thick layer of titanium and has a thickness of 150 nm, which is sufficient to show bulk behavior.
The channel can be filled by using a flow cell and a pump or just by putting a droplet on the inlet and capillary forces will fill the channel.
Please note that one of the Micrux cells is necessary to connect the electrode.
