  • Device and method for separating particles in a liquid, kit containing the device, and applications of the device
    Patent number: 12722126
    Abstract: The invention relates to a device, a method, and a kit for separating particles of different sizes in a liquid. The invention additionally relates to applications of the device. The device and the method involve the capability of binding particles to solid phase particles with different diameters in a liquid, whereby the hydrodynamic diameter of the solid-phase particles determines whether the particles can pass through pores of a filter element, the diameter of said pores being modifiable in a controlled manner (e.g., the diameter can be increased or decreased). Thus, particles of equal size (e.g., B-cells and T-cells) of a liquid can be separated from one another with a high degree of separation efficiency, wherein the particles can be separated simply, quickly, and inexpensively. High yields can be produced, and the particles can be provided in a therapeutically applicable liquid.
