Abstract
An apparatus including a fluidic input and a die including a microfluidic chamber, may receive a biologic sample. The microfluidic chamber may include a foyer to contain a portion of the biologic sample, and an inlet impedance-based sensor to detect passage of a cell of the biologic sample into the foyer. A target nozzle may eject a first volume, corresponding with a target concentration of cells of the biologic sample. A spittoon nozzle may eject a second volume of the portion of the biologic sample into a spittoon location. An output impedance-based sensor may be disposed within a threshold distance of the target nozzle to detect passage of a cell of the biologic sample into the target nozzle. Moreover, the apparatus may include circuitry to control firing of the target nozzle and the spittoon nozzle based on signals received from the inlet impedance-based sensor and the output impedance-based sensor.
