Abstract:
1. A microfluidic device for performing detection of a substance in a liquid sample, the device comprising: a base plate; a first lateral channel part extending along a first side of the base plate; a second lateral channel part extending along the first side of the base plate, wherein the second lateral channel part comprises a porous capillary suction structure; a sensor having a sensor surface area, wherein a cavity is formed above the sensor surface area, at least a part of the cavity being formed in the base plate, wherein the cavity extends at the first side of the base plate from a first area, wherein the cavity overlaps the first lateral channel part, to a second area, wherein the cavity overlaps the second lateral channel part, and wherein the cavity forms a flow path from the first lateral channel part along the sensor surface area to the second lateral channel part; wherein the porous capillary suction structure is adapted to exert a capillary force F wherein the cavity is adapted to exert a capillary force F
