摘要： In example implementations, an apparatus is provided. The apparatus includes a moveable stage, a print cartridge, a camera, and a processor. The moveable stage is to hold a well plate. The print cartridge holder is to hold a print cartridge that includes a print die over the moveable stage. The camera is located above the movable stage and the print cartridge holder. The camera is positioned such that the movable stage and the print die are within a field of view of the camera. The processor is to calculate a first offset a first offset of the well plate and a second offset of the print die. The movement of the movable stage is controlled by the processor in accordance with the first offset and the second offset.

摘要： Integrated microfluidic ejector chips and methods of use are provided. An example of an integrated microfluidic ejector chip includes a first set of microfluidic ejectors fed with a reference solution, and a second set of microfluidic ejectors fed with a sample solution. The first set of microfluidic ejectors and the second set of microfluidic ejectors are disposed on the integrated microfluidic ejector chip to print a pattern of proximately located spots on a sensor.

摘要： A system and a method for on-chip dilution of a calibration solution are provided. An exemplary system includes a microfluidic ejector chip. The microfluidic ejector chip includes a calibration reservoir to contain a calibration standard and a dilution reservoir to contain a dilution solvent. A first fluid control device couples the calibration reservoir to a mixing chamber, and a second fluid control device couples a dilution reservoir to the mixing chamber. The mixing chamber is fluidically coupled to a microfluidic ejector.

摘要： In an example method, an ordered array of microdots including an analyte printed on a surface of a surface-enhanced substrate of an analysis chip is probed with an excitation beam of electromagnetic radiation. Emitted radiation is detected from a number of microdots of the ordered array of microdots. Calibration data is generated for the analysis chip with respect to the analyte based on a detected shift in the emitted radiation as compared to the excitation beam.

摘要： A surface enhanced infrared absorption stage may include a substrate, a static island extending from the substrate and a movable nano finger extending from the substrate. The static island may have a plasmonically active island cap and a dimension parallel to the substrate of at least one micrometer. The movable nano finger may be aligned with the dimension. The movable nano finger may have a plasmonically active finger cap closable to less than or equal to 5 nm of the island cap.

摘要： An example method for measuring deformability of a cell via a pressure field, consistent with the present disclosure, includes flowing a biologic sample containing a plurality of cells along a first fluidic channel and into an intersection between the first fluidic channel and a second fluidic channel of a microfluidic device. The method includes introducing a pressure field at the intersection and into the first fluidic channel via the second fluidic channel and a plurality of apertures in a channel wall disposed in the intersection. The method further includes measuring deformability of a cell among the plurality of cells responsive to the introduction of the pressure field.
