Abstract: An immiscible droplet generation system may include a chip, a microfluidic channel integrated into the chip, an input to the microfluidic channel through which the microfluidic channel is to be filled with a first fluid that is to be moved through the microfluidic channel and a droplet generator. The droplet generator is integrated into the chip to generate a droplet of a second fluid, immiscible within the first fluid, and to inject the droplet into the first fluid in the microfluidic channel.

Abstract: A microfluidic device includes a chamber having a floor, a ceiling, and an inlet. The microfluidic device includes pillars extending from the floor to the ceiling of the chamber. Each pillar has a leading surface or corner, a trailing surface or corner opposite the leading surface or corner, and trailing side surfaces adjoining the trailing surface or corner. Each pillar is oriented along a corresponding ray intersecting the leading surface or corner and the trailing surface or corner. Adjacent pillars have a turn angle between the corresponding rays of the adjacent pillars, and each pillar has a pillar angle between the trailing side surfaces thereof. The turn and pillar angles are based on a fluidic contact angle to promote fluid flow from the inlet throughout the chamber during priming without fluidic pinning.

Abstract: Apparatuses may be used for nucleic acid amplification. An example apparatus may include an amplification chamber to contain a biochemical reaction associated with amplification of a biologic sample. The biologic sample may include a nucleic acid. The apparatus may also include a heater thermally coupled to the amplification chamber. The apparatus may also include a thermally conductive substrate in contact with the heater and including a liquid coolant passage to pass a liquid coolant through the thermally conductive substrate.
