The present invention relates to a microfluidic device for the analysis of a fluid sample, particularly for molecular diagnostic applications, the device comprising a substrate having a surface with at least one microchannel structure thereon, at least one detection, Having at least one device for driving the movement of the membrane, comprising a control and / or processing element, at least one containment chamber for receiving said fluid sample, at least one membrane and means for generating pressure and / or reduced pressure. The accommodating chamber may be formed between the thin film and the substrate, the accommodating chamber is smoothly connected to at least one microchannel, and the thin film is disposed on the substrate. The top surfaces of the two microchannel structures are covered with leakage resistance, so that the movement of the thin film Black cause pumping action to fluid located in said accommodating chamber in the channel, and / or causes a valve action on fluid directed into said microchannel. |
