    Abstract: A method of detecting passage of a particle into a target location includes receiving a sample on a die including a microfluidic chamber, the microfluidic chamber including a microfluidic path coupling a reservoir to a foyer, and moving the sample from the reservoir to the foyer by firing a nozzle fluidically coupled to the foyer. The method further includes detecting passage of a particle of the sample from the reservoir to the foyer via a first sensor disposed within the microfluidic path, and detecting passage of the particle into the target location via a second sensor disposed between the first sensor and the nozzle. The method includes recording in a dispense map, an indication of whether the target location includes a single particle or multiple particles based on signals measured by the first sensor and the second sensor.

    Abstract: According to an example, a microfluidic apparatus may include a channel, a foyer, in which the foyer is in fluid communication with the channel and in which the channel has a smaller width than the foyer, a sensor to sense a property of a fluid passing through the channel, a nozzle in fluid communication with the foyer, and an actuator positioned in line with the nozzle. The microfluidic apparatus may also include a controller to determine whether the sensed property of the fluid meets a predetermined condition and to perform a predefined action in response to the sensed property of the fluid meeting the predetermined condition.

    Abstract: A microplate lid is disclosed. An electronics board includes a plurality of board throughholes corresponding to well locations of a microplate. A cover plate includes a plurality of plate throughholes corresponding to respective board throughholes to define a plurality of plate-board throughhole pairs. The cover plate is located atop the electronics board. A plurality of directing lumens is at least partially defined by the cover plate. Each directing lumen corresponds to a respective plate throughhole. A plurality of user-perceptible array indicators is provided to the electronics board. Each array indicator is associated with a different plate-board throughhole pair than every other array indicator.

    Abstract: In one example in accordance with the present disclosure, a fluidic ejection controller is described. The fluidic ejection controller includes a firing board to pass electrical control signals for ejecting fluid from a fluidic ejection device. An ejection board of the fluidic ejection controller is electrically coupled to, and selectively removable from, the firing board to pass the electrical control signals to the fluidic ejection device. Electrical pins are disposed on the ejection board in a pattern that matches a pattern of electrical pads on the fluidic ejection device. The electrical pins interface with corresponding electrical pads to pass the electrical control signals from the ejection board to the fluidic ejection device.

    Abstract: In one example in accordance with the present disclosure, a fluid ejection die is described. The fluid ejection die includes a fluid feed slot to deliver fluid from a reservoir to an array of nozzles. Each nozzle of the array includes an ejection chamber, an opening, a fluid actuator disposed within the ejection chamber, and a fluid channel between the fluid feed slot and the ejection chamber. The fluid ejection die also includes a fluid cleaning structure to allow live cells in the fluid to pass to the nozzle while capturing other components.
