1. A microfluidic system, comprising:
an input channel having a first end and a second end to receive particles through the first end;
a sensor to detect particles in the input channel and generate, based on detection of particles, signals indicative of particle type;
a first output channel to collect particles of a first type at a first collection point and a second output channel to collect particles of a second type at a second collection point, each of the first output channel and the second output channel fluidically coupled to the second end of the input channel to receive particles from the input channel; and
a first pump associated with the first output channel, and a second pump associated with the second output channel, the first pump and the second pump operable to, based on the signals from the sensor, selectively stop or reverse particle flow and thereby (i) prevent particles of the first type in the second output channel from reaching the second collection point and (ii) prevent particles of the second type in the first output channel from reaching the first collection point.
