Abstract
Disclosed herein are systems and methods capable of identifying, tracking, and sorting particles or droplets flowing in a channel, for example, a microfluidic channel having a fluid medium. The channel and the fluid medium can have a similar refractive index such that they appear translucent or transparent when illuminated by electromagnetic radiation. The particles or droplets can have a refractive index substantially different from that of the channel and the medium, such that the particles or droplets interfere with the electromagnetic radiation. A sensor can be disposed adjacent to the channel to record the electromagnetic radiation. The sensor can be attached to a system for identifying, tracking, and sorting the droplets.
