| 20090026080 | APPARATUS AND METHOD FOR SEPARATING PARTICLES - A particle separator for separating different types of particles with different properties includes a channel unit including a flow channel through which a first fluid having particles with at least one physical characteristic and a second fluid that flows near the first fluid, and a plurality of outflow channels that are connected to the flow channel and that separate the fluid having passed the flow channel; and a field forming unit, installed adjacent to the flow channel, for separating the particles included in the first fluid from the first fluid and generating a non-uniform field so that the particles may flow together with the second fluid. | 01-29-2009 |
| 20090218222 | Free flow electrophoresis microchip, system and method - The present invention relates to a free flow electrophoresis microchip for the electrophoretic separation of charged components, a free flow electrophoresis separation system incorporating the same, and a free flow electrophoresis method of separating charged components, the microchip comprising: a separation chamber in which charged components are in use separated; a plurality of separation medium inlet channels having outlets fluidly connected to one, inlet side of the separation chamber through which flows of a separation medium are in use introduced into the separation chamber such as to develop a laminar flow having a flow direction through the separation chamber; a sample inlet channel having an outlet fluidly connected to the inlet side of the separation chamber through which a flow of a sample containing charged components is in use introduced into the separation chamber; a plurality of outlet channels having inlets fluidly connected to another, outlet side of the separation chamber opposite the inlet side thereof; and a magnetic field unit for providing a magnetic field substantially orthogonal to the flow direction of the separation medium; whereby charged components introduced into the separation chamber are deflected laterally across the separation chamber in dependence upon the charge, typically the electrophoretic mobilities or the iso-electric points, of the charged components. | 09-03-2009 |
| 20090321261 | DETECTION METHODS AND DETECTION DEVICES BASED ON THE QUANTUM CONFINEMENT EFFECTS - The invention describes detection methods and devices that comprise nanostructures and which detection mechanism is based on the quantum confinement effects. The nanostructures are built to have specific energy levels designed to match the energy levels of the targeted analyte that is to be detected. The analyte species are sensed by measuring charge or/and energy transfer between the species and the nanostructures, which will be proportional to the overlap between the density of states distribution in the nanostructures and the density of states distribution in the targeted analyte species. Different molecular species have different electronic density of states, so the charge or/and energy transfer between the targeted analyte and detector nanostructures will occur only for specific analyte which has the same electronic density of states as the detectors nanostructure. The detection methods, devices, and potential applications include, but are not limited to: chemical, biochemical, biological or biochemical analysis. | 12-31-2009 |
| 20100236931 | IMPROVEMENTS IN/OR RELATING TO A METHOD OF TREATING SLUDGES - The invention comprises a method of treating sludges which includes the steps of applying an electric field to the sludge to effect dewatering prior to further dewatering of the sludge. Typically the sludge comprises dilute phase sludge, and the electric field is a DC electric field. The pH of the sludge may be adjusted to between substantially 5 and substantially 6 prior to applying the electric field. | 09-23-2010 |
| 20110114490 | Bead Manipulation Techniques - The invention provides a method of redistributing magnetically responsive beads in a droplet. The method may include providing a droplet including magnetically responsive beads. The droplet may be provided within a region of a magnetic field having sufficient strength to attract the magnetically responsive beads to an edge of the droplet or towards an edge of the droplet, or otherwise regionalize or aggregate beads within the droplet. The method may also include conducting on a droplet operations surface one or more droplet operations using the droplet without removing the magnetically responsive beads from the region of the magnetic field. The droplet operations may in some cases be electrode-mediated. The droplet operations may redistribute and/or circulate the magnetically responsive beads within the droplet. In some cases, the droplet may include a sample droplet may include a target analyte. The redistributing of the magnetically responsive beads may cause target analyte to bind to the magnetically responsive beads. In some cases, the droplet may include unbound substances in a wash buffer. The redistributing of the magnetically responsive beads causes unbound substances to be freed from interstices of an aggregated set or subset of the magnetically responsive beads. | 05-19-2011 |

| 20120318671 | ELECTROHYDRAULIC AND SHEAR CAVITATION RADIAL COUNTERFLOW LIQUID PROCESSOR - Axially fed fluid is sheared during long residence time in a radial workspace between counter-rotating coaxial disk-shaped centrifugal impellers. Gases evolve in the fractal turbulence of a shear layer, which is forced between laminar boundary layers, and an axial suction pump axially extracts evolved noncondensables and volatiles through cores of radial vortices in the shear layer. Cavitation due to shear between the impellers kills pathogens by shock waves, microjets, OH radicals, and nearby UV light pulses. Oppositely charged electrodes bounding the workspace cause electroporesis and electrohydraulic cavitation. The electrodes are counter-rotating ridged armatures of disk dynamos, forming a dynamic capacitor having audio frequency pulsed electric fields. Electrode erosion by arcing is prevented by shear between the electrodes. | 12-20-2012 |
| 20150034485 | BEAD INCUBATION AND WASHING ON A DROPLET ACTUATOR - The present invention relates to bead incubating and washing on a droplet actuator. Methods for incubating magnetically responsive beads that are labeled with primary antibody, a sample (i.e., analyte), and secondary reporter antibodies on a magnet, on and off a magnet, and completely off a magnet are provided. Also provided are methods for washing magnetically responsive beads using shape-assisted merging of droplets. Also provided are methods for shape-mediated splitting, transporting, and dispensing of a sample droplet that contains magnetically responsive beads. The apparatuses and methods of the invention provide for rapid time to result and optimum detection of an analyte in an immunoassay. | 02-05-2015 |
