摘要： Apparatus for sorting and orienting sperm cells has a pair or walls in confronting relationship forming a flow chamber having inlet, a downstream outlet, and intermediate detector region. The inlet receives first and second spaced apart streams of input fluid and a third stream of sample fluid containing the cells to be sorted. The first and second streams have respective flow rates relative to third stream, such that the third stream is constricted forming a relatively narrow sample stream, so that the cells are oriented parallel to the walls. A detector detects desired cells and a sorter downstream of the detector for sorting the desired cells from the stream.

摘要： Holographic optical tweezers are used to position charge stabilized colloidal particles within a flow cell. Once the particles are positioned, fixation is accomplished by pumping an electrolyte solution or pH adjusted solution (or a combination of the two) into the sample cell. In the former, the Debye length is reduced and aggregation caused by the van der Waals attraction takes place. In the latter, the surface charge density of the suspension is reduced and aggregation caused by the van der Waals attraction takes place. This technique can be applied multiple times, and allows for the formation of two and three dimensional structures composed of multi-colloid types to be formed on or away from a substrate. The technique relies upon forces acting on virtually all colloidal dispersions making it applicable to a wide variety of colloid types and compositions, such as formation of photonic crystals, colloidal electronics, and bioengineered materials.

摘要： A method for manipulating particles (micro, nano, and pico) having one or more characteristics with an optical trap formed by modulating a laser beam with a Diffractive Optical Element (DOE). At least one characteristic of the material is selected; and a laser beam having a selected wavelength corresponding to the at least one selected characteristic of the material is generated. Values of the DOE are calculated corresponding to the at least one selected characteristic of the material. The beam and the DOE are modulated to produce a holographic optical trap having properties corresponding to the at least one selected characteristic; the trap is focused to a beam focus or selected spot size; and the beam focus is located near a particle location for trapping the particle therein.

摘要： The invention provides a method, apparatus and system for separating blood and other types of cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One of the exemplary methods includes providing a first flow having a plurality of blood components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first blood cellular component of the plurality of blood components into the second flow while concurrently maintaining a second blood cellular component of the plurality of blood components in the first flow. The second flow having the first blood cellular component is then differentially removed from the first flow having the second blood cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.

摘要： The present invention is related to an apparatus for the sorting of particles in a fluid medium flowing within a liquid-core waveguide, by combining customized light intensity patterns formed inside the waveguide, and diluting the suspension of particles (i.e., cells, blood, nanoparticles, etc.) flowing within the fluid medium of the waveguide. With this customized light intensity pattern, which controls the optical forces introduced by the light confined within the waveguide, and the control of the hydrodynamic forces introduced by the liquid flow (or multiple channel liquid flows), the sorting of particles can be achieved.
