Abstract
The present invention provides a microfluidic device, for instance for molecular sieving or for detecting a target substance in a sample fluid. The device comprises a first substrate (120) having a substantially flat first surface that is provided with first recesses (124), and a second substrate (128) having a substantially flat second surface that is provided with second recesses (130). At least some of the first recesses are filled with a porous material (114). Alternate first recesses and second recesses form a meandering channel for a sample fluid. The second recesses may be filled with a further porous material. In an embodiment, a capture substance for binding a target substance is arranged in or on the porous material.
