    Abstract: Examples include a fluid ejection device comprising a carrier, at least one fluid ejection die, and conductive traces at least partially embedded in the carrier. The carrier has a first portion and a second portion, where an angle of orientation between the first portion and the second portion is nonparallel. The first portion includes an array of openings formed through a top surface of the carrier. The second portion includes at least one die opening through a bottom surface of the carrier. The fluid ejection die is coupled to the second portion of the carrier. Fluid passages formed in a back surface of the fluid ejection die are exposed through the at least one die opening formed through the bottom surface of the carrier. The conductive traces have an array of contact points at first ends of the conductive traces. The array of contact points align with the array of openings of the first portion of the carrier such that the array of contact points are exposed through the array of openings. The conductive traces connect the fluid ejection die and the array of contact points.

    Abstract: A digital droplet PCR system is described. The digital droplet PCR system comprises a microfluidic cartridge comprising: a plurality of sample droplet generators, wherein each sample droplet generator is operable to partition a PCR mixture into a plurality of aqueous droplets dispersed in a carrier liquid, and wherein at least one sample droplet generator is operable to partition a PCR mixture that is different to a PCR mixture that is partitioned by at least one other sample droplet generator; a thermocycling chamber comprising an embedded heater, an inlet configured to receive the plurality of aqueous droplets from the plurality of sample droplet generators, and an outlet; and an optical readout zone fluidly connected to the outlet of the thermocycling chamber; and a pressure actuated pump configured to couple to and cause fluid flow through the microfluidic cartridge. A method of performing digital droplet PCR is also described.
