ABSTRACT:
A microfluidic device (1) comprising a hydrophilic microchannel structure (2) in which there is a functional unit that comprises a microconduit I (17) in which there is an inlet end (16), an outlet end (18), and a capillary stop function I (24) in the form of a local non-wettable surface area (44). The capillary stop function (24) defines a segment of microconduit I (17). Microconduit I (17) is within at least a part of this segment (46) divided into two or more microchannels (42). A part of the non-wettable surface area (44a,b) is associated with an inner wall of each of the microchannels (42).
