  • Systems and methods for undermedia repellency
    Patent number: 11951472
    Abstract: Systems, methods, compositions of matter, and kits for undermedia repellency are disclosed. In some cases, these involve a first volume of a first liquid presented in a second volume of a second liquid above a first location of a first surface. The first liquid, second liquid, and first location can have properties sufficient to give rise to undermedia perfect liquid repellency.
    Type: Grant
    Filed: June 15, 2018
    Date of Patent: April 9, 2024
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Chao Li, Jiaquan Yu, Theodorus Evan de Groot, David James Beebe
  • PARTICLE SEPARATION SYSTEMS AND METHODS
    Publication number: 20230112068
    Abstract: Magnetic levitation particle separation systems and methods for use with multi-channel flow cells. The system may include a core for receiving and holding the flow cell, with upper and lower clamps for securing the flow cell and positioning it relative to an array of magnets. The system is configured to image particle separation in processing channels of the flow cell, and to regulate the flow cell's temperature. The core may be removable as a single unit, facilitating reconfiguration of the system.

  • MAGNETIC PARTICLE ISOLATION DEVICE AND METHODS OF USE
    Publication number: 20210260577
    Abstract: The present invention provides for devices and methods of isolating particles. A fluidics particle isolation device is disclosed having a fluidic channel extending therethrough, wherein a segment of the fluidic channel is exposed to an asymmetric magnetic field such that when a solution containing the particles in a paramagnetic medium are passed through the magnetic field, the particles are isolated within the solution.
