    摘要： The invention relates to a microfluidic device for metering liquids into a microfluidic network. The microfluidic channels or chambers are at least partly formed by the introduction of suitable structures into a film above the substrate carrier, so that at least some of the flow of fluid through the network takes place above the plane of the substrate. In order to form a stable channel structure or chamber structure in the film, it is envisaged that in the edge zone between the unattached and attached portions a wedge of material is formed by the viscous flow of the film material as the film is bonded to the substrate, this wedge forming a transition between the chamber wall and the substrate and raising the chamber wall above the plane of the substrate. In one method of producing a finished microfluidic structure a flat planar film is laminated onto a flat sheet-like substrate. During the lamination a mask having at least one recess or opening is pressed onto the film and onto the substrate under pressure and/or under the effect of heat. The film is thereby brought to a temperature at which there is a viscous flow of film and/or substrate medium into the region of the recess or opening, so that a wedge of material is formed and the film bulges up in the region of the recess to form a chamber. The invention further relates to methods of metering at least one liquid in a microfluidic network, in which a capillary stop is overcome by actuating the film, the film being wetted as the capillary stop is removed.

    摘要： The invention relates to a microfluidic platform (1) having at least one means (12) for initiating a movement of a liquid (P), in particular a sample liquid, between at least two locations (100, 101) of the microfluidic platform (1).It is proposed according to the invention that the means (12) is embodied as an element of changeable volume and/or shape and is mounted on a cover-like component (11) that is movably connected to the microfluidic platform (1). By moving of the component (11) the element (12) can be brought into a position such that, by changing its volume and/or shape, it causes the liquid (P) situated at the location (100) to be moved at least partly from this location (100) to the other location (101).In this way a sample liquid (P) can be transferred from a sample application point (100) to a sample utilisation area (101) in a very simple and reliable manner.The invention further proposes a method by which a movement of a liquid between two locations can be initiated, while this can be done in particular using a microfluidic platform (1) according to the invention.
