1. A method, comprising:
- receiving a particle detection signal at a detector, the particle detection signal associated with optical characteristics of a particle in a first channel;
identifying, based on the particle detection signal, a sorting channel among a plurality of second channels coupled to the first channel for sorting the particle into the sorting channel based on the optical characteristics of the particle;
transmitting a sorting signal for sorting the particle from the first channel into the identified sorting channel;
receiving a verification signal at the detector, the verification signal associated with the presence of a detected particle in the sorting channel, the verification signal being an optical signal; and
verifying the sorting of the detected particle from the first channel into the sorting channel based on the verification signal.
