Classification: CPC B  G | IPC B  G

Claim 0:
1. A microfluidic particle processing chip assembly comprising;
a substrate;
a flow channel formed in the substrate, the flow channel having:
a focusing region for focusing a flow of particles within the flow channel;
an interrogation region at least partially downstream of the focusing region;
a switching region at least partially downstream of the interrogation region;
a first output channel; and
a second output channel;

a first side channel formed in the substrate and fluidically coupled to the flow channel;
a second side channel formed in the substrate and fluidically coupled to the flow channel opposite the first side channel;
a first bubble jet actuator fluidically coupled to the first side channel, the first bubble jet actuator including one or more heating elements disposed in the first side channel and configured to generate a pressure pulse in the flow in the switching region of the flow channel to switch particles into one of the first output channel or the second output channel; and
a second bubble jet actuator fluidically coupled to the second side channel, the second bubble jet actuator including one or more heating elements disposed in the second side channel and configured to generate a pressure pulse in the flow of the switching region of the flow channel to switch particles into one of the first output channel or the second output channel.
