Abstract
A cartridge for use in an electrowetting sample processing system, the cartridge having at least one inlet port for introducing an input liquid in an internal gap of the cartridge, wherein the gap has at least one hydrophobic surface and is configured to provide an electrowetting induced movement of a microfluidic droplet of input liquid, wherein the input liquid has a carrier liquid and a processing liquid and the gap has a capture zone that is configured to capture at least a part of the processing liquid as a microfluidic droplet by use of electrowetting force and the gap further has a transfer zone that is configured to provide a passage for the carrier liquid next to the microfluidic droplet, while processing liquid is captured in the capture zone.
