Patent number: 10780371Abstract: Emulsion breaking and phase separation is achieved by droplet adhesion. An emulsion breaking device includes a channel having distinct adjacent zones with distinctly different surface wettability characteristics, namely, solvophilic and solvophobic surfaces. The device is positioned such that the upstream portion of the device is configured to be wetted by the continuous phase of the emulsion, and the downstream portion of the device is configured to be wetted by the dispersed phase of the emulsion. As the emulsion flows from the upstream zone to the downstream zone, the change in surface wettability characteristics promotes adhesion of the dispersed phase as the dispersed phase wets the surface of the downstream portion of the channel, which results in breaking of the emulsion. Subsequent collection of the broken emulsion in a collection vessel results in separation of the disparate phases to facilitate their recapture and recycling.Type: GrantFiled: November 2, 2018Date of Patent: September 22, 2020Assignee: THE TRUSTEES OF PRINCETON UNIVERSITYInventors: Howard A.

Patent number: 10457975Abstract: Provided herein is a method and a system for separating suspended particles that have differing sedimentation velocities, comprising placing the particles inside a hollow device which upon rotation, spins the suspension into a thick film within which sedimentation of the particles occurs, rotating the hollow device at a speed and for a time that allows fast-sedimenting particles to sediment into a layer of more densely packed particles while some of the slow-sedimenting particles remain outside of the dense-particle-pack, and slowing the rotation of the hollow device in a manner to prevent remixing of the layer of dense-particle-pack with a layer containing some of the slow-sedimenting particles. This method may have application in many technologies including the rapid separation of bacteria from blood components.Type: GrantFiled: February 9, 2017Date of Patent: October 29, 2019Inventors: William George Pitt, Daniel S. McClellan, Colin G. Bledsoe, Mahsa Alizadeh

Patent number: 10429292Abstract: For analyzing a sample containing particles of at least two categories, such as a sample containing blood cells, a particle counter subject to a detection limit is coupled with an analyzer capable of discerning particle number ratios, such as a visual analyzer, and a processor. A first category of particles can be present beyond detection range limits while a second category of particles is present within respective detection range limits. The concentration of the second category of particles is determined by the particle counter. A ratio of counts of the first category to the second category is determined on the analyzer. The concentration of particles in the first category is calculated on the processor based on the ratio and the count or concentration of particles in the second category.Type: GrantFiled: March 17, 2014Date of Patent: October 1, 2019Assignee: Iris International, Inc.Inventors: Thomas H. Adams, Bart J. Wanders, John Roche, Harvey L. Kasdan

Patent number: 10421070Abstract: Embodiments of the present invention relate to methods and apparatuses for the discretization and manipulation of sample volumes that is simple, robust, and versatile. It is a fluidic device that partitions a sample by exploiting the interplay between fluidic forces, interfacial tension, channel geometry, and the final stability of the formed droplet and/or discretized volume. These compartmentalized volumes allow for isolation of samples and partitioning into a localized array that can subsequently be manipulated and analyzed.Type: GrantFiled: September 29, 2015Date of Patent: September 24, 2019Assignee: UNIVERSITY OF WASHINGTONInventors: Daniel T. Chiu, Dawn E. Cohen, Gavin D. M. Jeffries
