Claim Text:
1. A micromechanical particle manipulation device, formed on a surface of a substrate, comprising: a microfabricated, movable member formed on a surface of the substrate in a first plane, and having a first diverting surface, wherein the movable member moves from a first position to a second position in response to a force applied to the movable member, wherein the motion is substantially in the first plane parallel to the surface of the substrate; a sample inlet channel formed in the substrate and through which a fluid flows, the fluid including target particles and non-target material, wherein the flow in the sample inlet channel is substantially in the first plane parallel to the surface of the substrate; a sort output channel into which the microfabricated member diverts the target particles and a waste output channel into which the non-target material flows, and wherein the waste output channel is in a second, different plane than the movable member and the sample inlet channel, and wherein the waste output channel is located directly below at least a portion of the microfabricated member over at least a portion of its motion; and a sheath fluid inlet in fluid communication with the sample channel; and a focusing element coupled to the sheath fluid inlet, which is configured to urge the target particles into a particular portion of the sample channel.
