摘要： In an embodiment, a fluid ejection device includes a die substrate having first and second fluid slots along opposite substrate sides and separated by a substrate central region. First and second internal columns of closed chambers are associated with the first and second slots, respectively, and the internal columns are separated by the central region. Fluidic channels extending across the central region fluidically couple closed chambers from the first internal column with closed chambers from the second internal column. Pump actuators in each closed chamber pump fluid through the channels from slot to slot.

摘要： A method of detecting a defective nozzle within a nozzle array, may comprise grouping each nozzle with a number of other nozzles within the nozzle array, measuring fluid output from each group of nozzles with a fluid detector, individually regrouping each nozzle within a group of nozzles whose fluid output is detected as not being commensurate with the amount of fluid that should be ejected from that group with a number of known non-defective nozzles to form a number of subsequent groups, and measuring fluid output from the subsequent groups of nozzles to determine which nozzle among the subsequent groups of nozzles is defective.

摘要： An example device includes an array of sensor modules. A sensor module includes a body to be positioned in alignment with a planar target, a light source coupled to the body to emit light to the planar target along a source optical path, and a plurality of light sensors coupled to the body. Each light sensor is to sense a different wavelength of light received from the planar target along a sensor optical path. The sensor optical path is different from the source optical path. The bodies of the array of sensor modules are arranged in a planar tiling pattern with respect to a longitudinal axis of the planar target.

摘要： A printing fluid pen includes a plurality of fluid ports, a pressure regulator in fluid communication with a first fluid port, and a valve in fluid communication with a second fluid port. The first fluid port is to deliver printing fluid to a fluid ejection device, and the second fluid port is to direct printing fluid out of the pen. In response to negative pressure, the valve is to open to enable fluids within the pen to exit via the second port.

摘要： In one example in accordance with the present disclosure, a fluid manipulation system is described. The fluid manipulation system includes a microfluidic channel through which fluid is to flow. The fluid includes biomolecules to be separated. The fluid manipulation system also includes at least one array of biomolecule-capturing pillars disposed within the microfluidic channel to capture biomolecules from the fluid. Barriers rise from a surface of the microfluidic channel. The barriers span a width of the microfluidic channel orthogonal to a flow of the fluid to induce vortices in the fluid flow.

摘要： An example method, consistent with the present disclosure, includes receiving in a microfluidic channel, a fluid sample and a reagent, where the reagent includes a reporter nucleic acid labeled with a detectable ligand. The method further includes identifying a target nucleic acid in the fluid sample using a guide ribonucleic acid (gRNA) and a programmable nuclease immobilized in a side channel fluidically coupled to the microfluidic channel. Responsive to identifying the target nucleic acid in the fluid sample, the method includes causing cleavage of the detectable ligand, and detecting the detectable ligand from the cleaved reporter nucleic acid in the side channel.

摘要： The present disclosure is drawn to inertial pumps. An inertial pump can include a microfluidic channel, a fluid actuator located in the microfluidic channel, and a check valve located in the microfluidic channel. The check valve can include a moveable valve element, a narrowed channel segment located upstream of the moveable valve element, and a blocking element formed in the microfluidic channel downstream of the moveable valve element. The narrowed channel segment can have a width less than a width of the moveable valve element so that the moveable valve element can block fluid flow through the check valve when the moveable valve element is positioned in the narrowed channel segment. The blocking element can be configured such that the blocking element constrains the moveable valve element within the check valve while also allowing fluid flow when the moveable valve element is positioned against the blocking element.

摘要： A method of alignment and fusion of cells with an electrical field includes firing a first fluid dispenser of an electrofusion device until a first impedance sensor in a first microfluidic channel of the electrofusion device detects a presence of a first cell. The method includes firing a second fluid dispenser of the electrofusion device until a second impedance sensor in a second microfluidic channel of the electrofusion device detects a presence of a second cell. The method includes moving the first cell and the second cell into a merging chamber of the electrofusion device by firing a third fluid dispenser of the electrofusion device, in response to alignment of the first cell in the first microfluidic channel with the second cell in the second microfluidic channel. The method further includes fusing the first cell and the second cell in the merging chamber by creating an electrical field in the merging chamber.
