Abstract: In one example in accordance with the present disclosure, a particle dispensing system is described. The particle dispensing system includes a port to receive a number of fluid cartridges. Each fluid cartridge is to hold an amount of fluid to be ejected. The particle dispensing system also includes an optical verification system to determine, following ejection, a count of a number of particles ejected during an ejection event. The particle dispensing system also includes a controller to selectively activate a number of fluid ejectors to eject the amount of fluid.

Abstract: The present disclosure is drawn to a thermal inkjet printhead stack with an amorphous thin metal protective layer, comprising an insulated substrate, a resistor applied to the insulated substrate, a resistor passivation layer applied to the resistor, and an amorphous thin metal protective layer applied to the resistor passivation layer. The amorphous thin metal protective layer can comprise from 5 atomic % to 90 atomic % of a metalloid of carbon, silicon, or boron. The film can also include a first and second metal, each comprising from 5 atomic % to 90 atomic % of titanium, vanadium, chromium, cobalt, nickel, zirconium, niobium, molybdenum, rhodium, palladium, hafnium, tantalum, tungsten, iridium, or platinum. The second metal is different than the first metal, and the metalloid, the first metal, and the second metal account for at least 70 atomic % of the amorphous thin metal protective layer.

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.
