Publication number: 20080050283Abstract: A microfluidic device comprises pumps, valves, and fluid oscillation dampers. In a device employed for sorting, an entity is flowed by the pump along a flow channel through a detection region to a junction. Based upon an identity of the entity determined in the detection region, a waste or collection valve located on opposite branches of the flow channel at the junction are actuated, thereby routing the entity to either a waste pool or a collection pool. A damper structure may be located between the pump and the junction. The damper reduces the amplitude of oscillation pressure in the flow channel due to operation of the pump, thereby lessening oscillation in velocity of the entity during sorting process. The microfluidic device may be formed in a block of elastomer material, with thin membranes of the elastomer material deflectable into the flow channel to provide pump or valve functionality.Type: ApplicationFiled: August 21, 2007Publication date: February 28, 2008Applicant: California Institute of TechnologyInventors: Hou-Pu Chou, Anne Fu, Stephen Quake

Publication number: 20080050284Abstract: Apparatus for holding a sample to be tested includes a flat carrier element for acceptance of a sample, and a covering element. The carrier element is movable in relation to the covering element between a pushed-in position in which the covering element substantially accommodates the carrier element so as to shield the carrier element and the sample from the outside, and a pushed-out position in which the carrier element is moved out of the covering element so as to expose the sample. The carrier element and the covering element are secured to one another by a locking mechanism which includes at least one groove arranged on one member selected from the group consisting of carrier element and the covering element, and a protruding locking member arranged on the other member from the group consisting of carrier element and the covering element and constructed for movement in the groove.Type: ApplicationFiled: August 20, 2007Publication date: February 28, 2008Inventor: JOHANNES LORSCH
