Claim Text:
1. A particle separation device, comprising: a plurality of microfluidic channels, including a sample inlet channel through which a sample fluid flows, wherein the sample fluid includes one or more target particles and non-target material; an interrogation region disposed in the sample inlet channel, wherein the one or more target particles are distinguished from non-target material in the fluid stream; a microfabricated fluidic valve formed on a surface of the substrate, wherein the microfabricated fluidic valve redirects the target particles into one of a plurality of output channels, based on a signal from the interrogation region, and wherein the motion of the fluidic valve is substantially in a first plane parallel to the surface of the substrate; wherein the sample inlet channel is substantially also in the first plane parallel to the surface of the substrate, and wherein at least one of the output channels is in a second, different plane than the fluidic valve and the sample inlet channel; a carrier fluid inlet which supplies a carrier fluid to surround the one or more target particles with a quantity of carrier fluid; and an output structure that dispenses a plurality of discrete quantities of carrier fluid and the one or more target particles onto a receptacle.
