Abstract (en)
[origin: WO2010142700A1] The invention relates to a microfluidic device (1) for transporting a product by diffusion in a porous substrate (2) from a product (F) injection area (ZI) to a product intake area (ZA), connected by a product channelling area (ZE). The porous substrate according to the invention has a free surface (4) which is partially covered with a mask (5, 6, 7) that is impervious to the product and which extends from the injection area (ZI) to the intake area (ZA) such as to define the product channelling area (ZE) in the substrate, in order to enable product evaporation via an uncovered portion (8, 9) of the free surface (4).
