Abstract: A system and method for managing a microfluidics device. The system includes a microfluidics device; a controller with a first processor which receives outputs from the microfluidics device and provides inputs to the microfluidics device; and a computing device with a second processor and an application program interface (API). The computing device provides instructions to the controller using the API. The instructions are executed by the first processor to produce real-time outputs to the microfluidics device.

Abstract: In one example in accordance with the present disclosure, a system is described. The system includes a fluidic die to advance across an ejection path relative to a substrate. The fluidic die includes a channel to contain a portion of a sample fluid, a sensor to detect passage of a particle within the sample fluid into the channel, and an ejection device. The ejection device is to eject the particle. The system also includes a controller. The controller identifies discrete locations along the ejection path as waste sites as the fluidic die advances along the ejection path. This is done by 1) classifying the particle as a target particle or a non-target particle, 2) upon identification of a target particle, ejecting the target particle to a target site of the substrate, and 3) upon identification of a non-target particle, ejecting the non-target particle to a waste site.

Abstract: Example implementations relate to a microfluidics sensing system. For example, a microfluidics sensing system may include a portable computing device to execute a microfluidics application, a microfluidic chip coupled to the portable computing device, the microfluidic chip including a microfluidic pumping and sensing region to perform a test on a biologic sample, and a printed circuit board (PCB) on a microfluidic reader to instruct the microfluidic pumping and sensing region to perform the test based on a command received from the microfluidics application.

Abstract: Examples herein provide a device. The device includes a testing cassette including: a microfluidic channel connecting an input port at a first end to at least one sensor area at a second end, the channel is to allow a blood sample to flow from the input port to the at least one sensor area; at least two electrodes; and a micro-fabricated integrated sensor, wherein when an electrical potential difference is applied over the blood sample, the sensor is to measure, over a duration of time, an electrical signal passing through the blood sample as the blood sample flows from the input port to the at least one sensor area and begin to coagulate, thereby obtaining a measurement function as a function of time. The device includes a processor to correlate the measurement function to a characteristic of the blood sample.
