Abstract:
1. A method for producing a microfluidic system, containing at least one microfluidic component having at least one microfluidically active surface, comprising: A) providing a microfluidic composite substrate having a connection side, comprising at least one microfluidic component introduced into a polymer composition, the microfluidic component defining a microfluidic component channel structure and including a microfluidically active surface on one side of the microfluidic component that defines a plurality of openings fluidly connected to each other via the microfluidic component channel structure, the plurality of openings in the microfluidically active surface being the only openings to the microfluidic component channel, wherein the microfluidically active surface of said component forms a part of the connection side of the microfluidic composite substrate such that the plurality of openings are exposed on the connection side of the microfluidic composite substrate; B) providing a mating substrate having a connection side for connection to the microfluidic composite substrate; C) providing microfluidic structures on a connection side of at least one of the composite substrate in the polymer composition and the mating substrate that define a microfluidic substrate channel structure in the microfluidic system; and D) connecting the microfluidic composite substrate and the mating substrate by their connection sides to form the microfluidic substrate channel structure such that the microfluidic substrate channel structure fluidly connects the plurality of openings in the microfluidically active surface to fluidic-through contacts that are configured to fluidly connect the microfluidic components to components outside the microfluidic system.
