    Abstract: In example implementations, an apparatus is provided. The apparatus includes a channel, an opening in the channel, and a heating element aligned with the opening on opposite sides of the channel. The channel contains a droplet of a first liquid containing a particle, wherein the droplet is carried within a second liquid in the channel. The heating element is to heat the first liquid to generate a vapor in the first liquid to eject the droplet of the first liquid through the opening.

    Abstract: The present disclosure relates to a microfluidic device including a microfluidic substrate and dry reagent-containing polymer particles. The microfluidic substrate includes a microfluidic-retaining region within the microfluidic substrate that is fluidly coupled to multiple microfluidic channels. The dry reagent-containing polymer particles include reagent and a degradable polymer. The reagent is releasable from the degradable polymer when exposed to release fluid. The dry reagent-containing particles are retained within the microfluidic substrate at the microfluidic-retaining region in position to release reagent into the egress microfluidic channel upon flow of release fluid from the ingress microfluidic channel through the microfluidic-retaining region.

    Abstract: An example device includes a microfluidic channel and a movable element retained in the microfluidic channel to move from a first position to a second position by fluid flow through the microfluidic channel. The device includes a sensor to take a sensor reading to determine fluid flow through the microfluidic channel. The device includes a microfluidic pump to return the movable element from the second position to the first position. The device includes a controller to actuate the microfluidic pump and to determine a flow rate of the fluid flow through the microfluidic channel based on the sensor reading.

    Abstract: A microfluidic bead-packing method includes activating a first micropump to transfer active microbeads through an inlet microchannel from a bead suspension reservoir to an adsorbing channel; packing the microbeads in the adsorbing channel; and activating a second micropump to reverse flow through at least a portion of the inlet microchannel and to transfer a sample fluid through the inlet microchannel from a sample reservoir to the adsorbing channel such that the sample fluid interacts with the packed microbeads.

    Abstract: An example self-priming microfluidic structure can include a microfluidic channel including a floor and a ceiling. A channel height is defined as a distance between the floor and the ceiling. A channel height step can be in the floor, or ceiling, or both. The channel height downstream of the channel height step can be greater than the channel height upstream of the channel height step. An interior pillar can be positioned in the microfluidic channel extending from the floor to the ceiling. The interior pillar can include a widening portion at an upstream end of the interior pillar and a tapering portion at a downstream end of the interior pillar. The interior pillar can overlap the channel height step so that the interior pillar is partially upstream of the channel height step and partially downstream of the channel height step.

    Abstract: In example implementations, an apparatus is provided. The apparatus includes a channel, a reagent chamber, a synthetic jet channel, and an energy source. The channel is to hold a cell. The reagent chamber is coupled to the channel and stores a reagent. The synthetic jet channel is coupled to the channel and the reagent chamber. The energy source is located in the synthetic jet channel to heat a liquid in the synthetic jet channel to create a synthetic jet that carries the reagent through towards the cell to inject the reagent into the cell.
