Abstract: Examples herein involve amplification and detection of nucleic acids using a microfluidic reaction chamber. An example apparatus includes a reaction-chamber circuit to process a reagent and a biologic sample for amplification of nucleic acids. The apparatus further includes a plurality of capillaries to pass the reagent and the biologic sample through the microfluidic reaction chamber. A valve control system may selectively control each of a plurality of valves to cause the reagent and the biologic sample to selectively move through the microfluidic reaction chamber for the amplification of the nucleic acids according to a particular timing sequence. In various examples, a trapping region disposed in the microfluidic reaction chamber secures the nucleic acids in the microfluidic reaction chamber for amplification using the reaction-chamber circuit.

Abstract: A fluidic die may include a fluid channel layer defining a number of fluid channels therein, a slot layer disposed on a side of the fluid channel layer, and a first fluid slot and a second fluid slot defined in the slot layer. At least one of the fluid channels fluidically couples the first fluid slot to the second fluid slot. The first fluid slot and the second fluid slot are defined in the slot layer along a length of the fluidic die.

Abstract: A fluidic die may include a at least one actuator, and fluid flow architecture to flow a first fluid through at least one fluidic channel, and flow a second fluid through the at least one fluidic channel to form a laminar flow between the first fluid and the actuator. The at least one actuator forms a drive bubble from the second fluid to cause the first fluid to be ejected from the fluidic die.
