Abstract: Examples include a fluid ejection die embedded in a molded panel. The fluid ejection die comprises a substrate, and the substrate includes an army of nozzles extending therethrough. The substrate has a first surface in which nozzle orifices are formed and a second surface, opposite the first surface, in which nozzle inlet openings are formed. The fluid ejection die is embedded in the molded panel such that the first surface of the substrate is approximately planar with a top surface of the molded panel. The molded panel has a fluid channel formed therethrough in fluid communication with the nozzle inlet openings of the array of nozzles.

Abstract: Examples include polymerase chain reaction (PCR) devices. Example PCR devices comprise a fluid input, a fluid output, and a set of microfluidic channels that fluidly connect the fluid input and the fluid output. Each microfluidic channel comprises a reaction chamber, and examples further comprise at least one heating element, where the at least one heating element is positioned in the reaction chamber of each microfluidic channel. The at least one heating element is to heat fluid in the reaction chamber of each fluid channel, and the at least one heating element is to pump fluid to the reaction chamber and from the reaction chamber of each microfluidic channel.

Abstract: A device for microfluidic transport includes a first fluid reservoir, a second fluid reservoir spaced from the first fluid reservoir, a main fluid channel communicated with the first fluid reservoir and the second fluid reservoir, an auxiliary fluid channel communicated with the main fluid channel, and a fluid actuator within the auxiliary fluid channel asymmetric to the main fluid channel such that operation of the fluidic actuator is to induce fluid flow in the main fluid channel from the first reservoir toward the second reservoir.

Abstract: In an example implementation, a method of controlling a microfluidic valve includes activating a first inertial pump at a first frequency, and a second inertial pump at a second frequency to create a first fluid flow pattern within a microfluidic valve. The method also includes adjusting at least one of the first frequency and the second frequency to change the first fluid flow pattern to a second fluid flow pattern.
