Abstract

A liquid-transport device has a liquid-tight support (12) on which there is applied a start zone (24; 24′) for applying transport liquid to be transported and a target zone (26, 28; 26a-e) into which the transport liquid is to be transported and also a conduction zone that extends between the start zone (24, 24′) and the target zone (26, 28; 26a-e) and that has a microporous transport layer (14) in which the transport liquid flows by capillary force from the start zone (24; 24′) to the target zone (26, 28; 26a-e). The conduction zone has a multiplicity of open flow channels separated from one another by microporous bridges having open-pored side walls.
