TL;DR: In this article, a microfluidic device and a method for use thereof for the separation, purification and concentration of components of fluid media was described, in particular for processing blood samples.
Abstract: The invention relates to a microfluidic device and to a method for use thereof for the separation, purification and concentration of components of fluid media. The invention relates in particular to a microfluidic device and a method for processing blood samples. A microfluidic device is provided, comprising: a structured component (1), which is formed as a planar body; a microfluidic channel system (2), which is configured in the structured component (1); at least one component (3) applied to a surface of the structured component (1); at least one porous functional element (5); and at least one fluidic interface (4.1, 4.2, 4.3), which is arranged on the structured component (1), for feeding media into the microfluidic channel system (2).

TL;DR: A fluidic system as mentioned in this paper contains a chamber with movable elements, which can be used for taking in, pumping, diluting, mixing and dispensing liquids or gases, and moreover can be dispensed from or taken into the system, by moving the movable element both into and out of the chamber.
Abstract: A fluidic system contains a chamber with movable elements. The chamber is connected to a duct. The system contains at least one structured component and at least one element affixed thereto and at least one fluidic interface which can be closed by means of a cap or valve. Liquids or gases can be moved via one or more ducts, and moreover can be dispensed from or taken into the system, by moving the movable element both into and out of the chamber. A liquids reagent reservoir can be connected to the pump chamber or the duct system for dilution purposes and also for supplying reaction components or scrubbing liquids. The system can be used for taking in, pumping, diluting, mixing and dispensing liquids or gases. There is provided an additional element (filters, membranes, frits or similar elements) or integrated reagents which can be arranged in the form of an array of identical or different reagents in order to permit separation, filtration, fractionation, enrichment of liquids and their constituents and also modification of liquids and/or their constituents and analysis of the contents of the liquids. The system can be operated manually or by means of simple devices or appliances.
