Abstract: Drop detection are disclosed. An example liquid dispensing device includes a controller to control dispensing of a first drop from a first orifice and a second drop from a second orifice, a sensor to monitor the first orifice to detect at least one of a presence or an absence of a drop from the first orifice and, in response to the sensor detecting an absence of the first drop, the controller is to classify the first orifice as at least one of occluded or non-functioning.

Abstract: A microfluidic device may include a microfluidic channel including an electrode placed at opposite ends of the microfluidic channel to create an electrical field within the channel and an ejection device to eject at least one cell porated within the electrical field. A cassette may include a substrate, a die coupled to the substrate, a microfluidic channel defined within the die, the microfluidic channel including a necked portion to receive a cell therein and at least two electrodes each placed at a first and a second end of the microfluidic channel to apply an electric field to the cell above a proration threshold and a cell ejection device to eject the cell from the die.

Abstract: In one example in accordance with the present disclosure, a fluid ejection controller is described. The fluid ejection controller includes a firing board to pass control signals to a fluid ejection device to eject fluid from the fluid ejection device. A mount pivotally holds the firing board between a disengaged position where electrical pins of the firing board are not in contact with electrical pads of the fluid ejection device and an engaged position where the electrical pins are in contact with the electrical pads. The mount includes a slot to receive the fluid ejection device and at least one biasing spring to bias the firing board away from the fluid ejection device during insertion of the fluid ejection device. The fluid ejection controller also includes a handle coupled to a cam shaft to move the firing board between the disengaged position and the engaged position.

Abstract: A fluid ejection system, in an example, includes at least one nozzle of at least one die from which a fluid is ejected and at least one nanowell at which the at least one nozzle ejects an amount of fluid. A method of dispensing a fluid, in an example, includes addressing at least one nanowell with at least one nozzle of at least one die, and depositing a fluid in the nanowell with the at least one nozzle.

Abstract: In example implementations, a method is provided. The method may be executed by a processor of a fluid dispensing apparatus. The method includes dispensing a fluid onto a surface from a dispenser during an alignment procedure. The surface is ejected for alignment verification. The surface is then received for re-execution of the alignment procedure after the alignment verification. The dispenser is re-used to dispense fluid onto the surface during re-execution of the alignment procedure.
