Devices and Methods for Sensing and Sorting Particles

Abstract: example microfluidic devices and methods for sensing and sorting of particles in a microfluidic channel are disclosed. an example microfluidic device includes a substrate with a microfluidic channel having an inlet, a first region, and a second region, the microfluidic channel being coupled with output channels. the example microfluidic device also includes one or more sensors located adjacent to the first region for sensing respective particles, and an inlet piezoelectric actuator located adjacent to the inlet and configured to facilitate input mixing of samples. the example microfluidic device further includes a first piezoelectric actuator located adjacent to the second region and configured to deflect the respective particles to respective output channels based on signals from the one or more sensors, and a set of one or more outlet piezoelectric actuators located adjacent to at least one of the output channels and configured to facilitate ejection of the respective particles.
