  • Publication number: 20230166261
    Abstract: Described are systems and methods for particle sorting. An array may comprise a substrate with a first surface and a second surface opposite to the first surface. The substrate may comprise a plurality of pores defining lumens extending from the first surface to the second surface. The plurality of pores can be configured to receive a sample solution comprising a plurality of particles. The array may further comprise a surface material provided at or adjacent to the first or second surfaces. The surface material may comprise a plurality of materials that are configured to modify a wetting behavior of the sample solution or the plurality of particles at or adjacent to said first or second surfaces, such that one of the first or second surfaces is hydrophilic, and the other of the first or second surfaces is hydrophobic.

  • Publication number: 20220250074
    Abstract: Methods and devices for creating monolayer arrays of cells or particles are described which may be used for high-throughput cell sorting and analysis, or other particle sorting applications. A cell loading system is described, the system comprising a porous mesh having a plurality of openings arranged in a random or repeating pattern across a surface. The porous mesh is used for preparing a layer of target particles, e.g., cells, distributed and spaced apart in a two-dimensional configuration on or within the mesh. Each of the plurality of openings in the mesh is configured to receive and permit a target particle to pass through when a fluid containing the target particles is dispensed on the surface of the mesh.

  • Publication number: 20210263061
    Abstract: A method is provided for detecting one or more analytes in a sample. The method relies, in part, on the ability of functionalized particles added to the sample to partially or completely inhibit the transmission of electromagnetic radiation into and out of the sample through a detection surface in a reaction vessel containing the sample. In a microarray format, the invention can be used to screen millions, billions or more biological elements, such as an organism, cell, protein, nucleic acid, lipid, saccharide, metabolite, or small molecules. Methods, apparatuses and kits are described.

  • Publication number: 20210244763
    Abstract: The present disclosure provides distinct therapeutic populations of cells that form a pharmaceutical composition useful in hematopoietic stem/progenitor cell transplant. For example, the present disclosure provides a therapeutic population of cells, comprising an enriched population of hematopoietic stem/progenitor cells, memory T cells, regulatory T cells, and wherein the population of cells is depleted of naïve conventional ??-T cells. The present disclosure further provides methods of treatment using the therapeutic population of cells. In other embodiments, the present disclosure provides methods of producing a therapeutic population of cells.
