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.
