Method and device for targeted process control in a microfluidic processor having integrated active elements

摘要

The invention relates to a microfluidic micromechanical system having integrated active elements (7) and a method for microfluidic process control in a microfluidic micromechanical system. According to the invention, the microfluidic system comprises integrated active elements (7), which can be activated without auxiliary energy by means of ambient variables that can be influenced and which are designed to bring about active functions as a result of the change of the swelling state thereof or the mechanical properties thereof. The microfluidic micromechanical system further comprises at least one structural support (2) having at least one first (3) and one second (4) channel, wherein a reaction chamber (6) bounded by active elements (7) is formed in an overlapping region (5) of the first and second channels.

1. Microfluidic, micro-chemomechanical system with integrated active elements (7) that can be activated and increased and decreased in size via influenceable environmental variables without the use of auxiliary energy and that bring about active functions via a change in their swelling state or their mechanical characteristics, said active functions determining a time-related sequence and time-related behavior of liquids in the system, comprising
at least one structure support (2) with at least one first channel (3), a cover (2a) that at least partially covers the structure support (2), and at least one second channel (4), wherein the second channel (4) is arranged on the structure support (2) or the cover (2a), wherein the channels (3, 4) form reservoir chambers (9, 10, 19) limited by active elements (7) in each case, said reservoir chambers being arranged in such a way that they have at least one overlay area (5) vis-a-vis one another and together form a reaction chamber (6), and wherein the size increases and decreases of the active elements fully or partially block and unblock the channels and are controlled by the dimensions and materials of the active elements.
