1. A particle sorting chip comprising:

  • a duct configured to convey particles in a stream, the duct including an inlet and a plurality of flow-through outlet channels, wherein the particles normally flow from the inlet into a first outlet channel of the plurality of flow-through outlet channels; and

    a first chamber in fluid communication with the duct via a first side opening, the first side opening positioned upstream of the plurality of flow-through outlet channels,wherein the first chamber is an actuator chamber configured to selectively discharge a transient pressure pulse during a switching operation via the first side opening to a selected particle having a predetermined characteristic,wherein the transient pressure pulse separates the selected particle from the stream of particles continuing to flow into the first outlet channel and deflects the selected particle into a second outlet channel of the plurality of flow-through outlet channels, andwherein, in the absence of the switching operation, fluid does not flow through the first side opening.
