The present invention relates to droplet-based particle sorting. According to one embodiment, a method of providing a droplet comprising a single cell is provided, wherein the method includes providing a droplet comprising a suspension of cells on an electrowetting droplet actuator surrounded by an oil medium, dispensing from the droplet to provide a dispensed droplet, determining whether the dispensed droplet on the electrowetting droplet actuator comprises a single cell, and sorting the dispensed droplet on the electrowetting droplet actuator based on the results of the determining step using electrowetting-mediated droplet operations.
