Microfluidic system or microfluidic device and method for producing a microfluidic system or a microfluidic device

摘要

The invention relates to a method for producing a microfluidic system or a microfluidic device (30) with at least one channel (20). The method comprises providing a base layer (7), providing a deformable intermediate layer (13), providing a cover sheet (4) and laminating the base layer (7), the intermediate layer (13) and the cover sheet (4) so that a back surface of the intermediate layer (13) is attached to a front surface of the base layer (7), and a back surface (4b) of the cover film (4) faces a front surface (13a) of the intermediate layer (13) opposite to the back surface thereof; is attached, whereby a layer structure is formed, which has the base layer (7), the intermediate layer (13) and the cover sheet (4). Furthermore, the method comprises applying pressure to the front surface (13a) of the intermediate layer (13) through the cover film (4) so that the intermediate layer (13) is deformed, whereby the at least one channel (20) is formed. The invention also relates to a microfluidic system or microfluidic device (30) produced by this method.
