| 摘要 |
The present invention relates to a method for producing a microfluidic device, comprising the following method steps: a) arranging a thermoplastic elastomeric film (1) between a base substrate (2) and a cover substrate (3), wherein at least one of the substrates (2, 3) has at least one depression (4, 5) for forming a microfluidic chamber having a depression opening (4a, 5a) on the side (2a, 3a) of the substrate (2, 3) facing the elastomeric film (1), b) applying pressing power to the arrangement such that the elastomeric film (1) is compressed between the base substrate (2) and the cover substrate (3), in which process the thickness (d0) of the elastomeric film (1) is reduced, c) forming, by means of laser beam welding, at least one weld joining the thermoplastic elastomeric film (1), the base substrate (2) and the cover substrate (3), and d) removing the pressing power, in order to prevent the formation of capillaries between the base substrate (2) and the cover substrate (3). |
