Abstract: According to an example, a microfluidic apparatus may include a fluid slot and a foyer that is in fluid communication with the fluid slot via a channel having a relatively smaller width than the foyer. The microfluidic apparatus may also include an electrical sensor to measure a change in an electrical field caused by a particle of interest in a fluid passing through the channel from the fluid slot to the foyer, an actuator to apply pressure onto fluid contained in the foyer, and a controller to receive the measured change in the electrical field from the electrical sensor, determine, from the received change in the electrical field, an electrical signature of the particle of interest, and control the actuator to control movement of the particle of interest based upon the determined electrical signature of the particle of interest.

Abstract: A microfluidic diagnostic device may comprise a fluid inlet to receive a fluid from a fluidic slot, a main microfluidic channel fluidly coupled to the fluid inlet, and a main microfluidic pump interposed between the fluid inlet and the main microfluidic channel to continuously circulate a fluid through the fluidic slot, fluid inlet, and main microfluidic channel wherein the width of the fluid inlet is different from the width of the main microfluidic channel. A diagnostic device, comprising a fluidic slot, a fluid inlet fluidly coupled to the fluidic slot, a main channel fluidly coupled to the fluid inlet, and an inlet pump interposed between the fluid inlet and channel wherein the cross-sectional area of the fluid inlet is relatively larger at least one point than the cross-sectional area of the channel.

Abstract: Example implementations relate to coagulation sensing. For example, a microfluidic chip for coagulation sensing may include a microfluidic channel, an outlet at an end of the microfluidic channel having an air interface, and an impedance sensor located within the microfluidic channel and within a particular proximity to the air interface, the impedance sensor to determine a stage of a coagulation cascade of a blood sample flowing through the microfluidic channel to the impedance sensor.
