Abstract
A device for controlling a flow of fluids through n=2microfluidic 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. A cooling element is configured to control fluid received in the microfluidic channels.
