Abstract: An array for a microfluidic device is disclosed which has depressions that are formed in parallel rows in one side of an array. The side has, in adjacent rows, in each case at least one different surface property. The microfluidic device has at least one array chamber in which the array is arranged such that the rows extend parallel to a flow direction of a fluid. To operate the microfluidic device, a fluid is guided through the array chamber such that it flows along the rows over the side of the array.

Abstract: The invention relates to a cooling device (1) for cooling components (101), comprising a baseplate (2) which can be heat-conductively connected to a component (101) to be cooled, a deflection region (3), an intermediate region (4) between the baseplate (2) and the deflection region (3), and a cooling element (5), which is formed in a meandering shape and has multiple central segments (51) and multiple deflection segments (52), wherein the central segments (51) each extend from the baseplate (2) to the deflection region (3), wherein the deflection segments (52) each create a change of direction within the baseplate (2) and within the deflection region (3) and connect two respective central segments (51) to one another, wherein the cooling element (5) is filled with a working material, which is simultaneously gaseous and liquid in the cooling element (5), and wherein the central segments (51) have a plurality of channels (53).

Abstract: A device is for determining a control protocol for a microfluidic system using temperature influences. The microfluidic system includes a first chamber for a fluid, and a first heating element configured to influence a temperature of the fluid in the first chamber. A model is provided which is parameterized with a parameter set, and which is configured to determine an influence of a first temperature and an influence of a second temperature on a temperature profile in the fluid in the microfluidic system, if same is controlled according to the control protocol. A target is provided for the temperature profile. The parameter set is determined at which a temperature profile calculated with the model fulfills the target. The parameter set comprises at least one parameter of the control protocol which specifies the first temperature and/or the second temperature.

Abstract: A system for transferring a sample into a microfluidic system, including a sample loading chamber, wherein a first sub-volume of the sample loading chamber is separated from at least one second sub-volume of the sample loading chamber by a filter module. The first sub-volume forms a pressure chamber provided for the loading of the sample, and there is at least one second sub-volume for providing the microfluidic system with the sample.
