    Abstract: A microfluidic device is provided for inducing the separation of constituent elements from a microfluidic sample by introducing phase changes in the microfluidic sample while contained in a microfluidic channel in the device. At least a portion of the microfluidic sample is frozen to cause fractional exclusion of the constituent element from the frozen portion of the microfluidic sample. Different portions of the microfluidic sample may be frozen in different sectors and at different times in order to cause movement in a desired direction of the separated constituent element. Portions of the microfluidic sample may be frozen in a sequential order of adjacent sectors within the microfluidic channel in order to cause sequential movement of the excluded constituent element toward one portion of the microfluidic channel. The frozen portion of the microfluidic sample is then thawed, wherein the separated constituent element remains substantially separated from the thawed, purified microfluidic sample.

    Abstract: An acoustic focusing capillary includes a capillary coupled to at least one vibration source possessing a groove. A method of manufacturing such an acoustic focusing capillary includes providing a capillary and a vibration source, machining a groove into the vibration source, and coupling the vibration source to the capillary at the groove. Another method relates to focusing a particle stream and includes flowing a sheath fluid into an outer confine of a capillary, flowing a particle stream into a central core of the capillary, and acoustically focusing the particle stream by applying acoustic radiation pressure to the particle stream at a first location along the capillary. The particle stream may be further focused by hydrodynamically focusing it at a second location along the capillary downstream of the first location.
