Abstract: A device for controlling a flow of fluids through n=2m microfluidic channels, m being a natural number>0 includes a substrate having the microfluidic channels therein. Each channel includes m contact points. A respective heating element corresponds to each contact point. Each of a plurality of m pairs of conductor paths corresponds to a respective contact point of each of the microfluidic channels. Each pair includes a first conductor path that is in contact with a respective first half of the heating elements that correspond to the respective contact points of each microfluidic channel and a second conductor path that is in contact with a respective second half of the heating elements that correspond to the respective contact points of each microfluidic channel. A respective control line corresponds to each of the m pairs of conductor paths, where each control line is operable to actuate the corresponding pair of conductor paths with a switching status TRUE or a switching status FALSE.

Abstract: A device for creating a microfluidic channel structure includes two plates forming a chamber between the two plates. The chamber has at least one inlet for feeding a fluid into the chamber and at least one outlet for discharging the fluid out of the chamber. A cooling element is associated with at least one of the two plates for converting fluid disposed in the chamber into a solid. A plurality of heating elements is associated with at least a first of the two plates and distributed so as to provide, by a heating up of some of the heating elements so as to convert areas of the solid that are in a vicinity of the heating elements to the fluid, a channel structure leading from the at least one inlet through the chamber to the at least one outlet. The channel structure is configured to convey fluid flow.
