  • Patent number: 11920115
    Abstract: An array of magnetic or paramagnetic micro-elements comprised of polysilsesquioxane is described having ultra-low-autofluorescence and other optical properties to improve microscopic imaging of cells or other objects present on the array. These materials are also amenable to chemical modification allowing surface attachment of affinity capture moieties or chemical reporters for selective binding or analysis of cells, macromolecules or other targets.
    Type: Grant
    Filed: August 29, 2018
    Date of Patent: March 5, 2024
    Assignees: The University of North Carolina at Chapel Hill, Cell Microsystems, Inc.

  • Publication number: 20230212556
    Abstract: Systems and methods for associating single cell imaging data with RNA transcriptomics. Single cells are isolated into microwells with a microbead having oligonucleotides conjugated on its surface. Each oligonucleotide includes a cell identifying optical barcode that is unique to that bead and binding sequence for RNA capture after cell lysis. The system is configured for loading single cells into the microarray and for flowing cell lysis buffers and other reagents into the microarray for performing RNA library sample preparation. The system is also configured for lowing optical hybridization probes that are complementary to the cell identifying optical barcodes and optically labeled onto the microwell array and for obtaining images of the microwells in response to the probes. The system and unique cell identifying optical barcodes and complementary optical hybridization probes facilitate a link between phenotypic imaging of cells resident on the microwell array with single cell whole transcriptome sequencing.

  • Publication number: 20200080046
    Abstract: Embodiments of the disclosed subject matter provide an automated method and system to isolate and collect cells using computerized analysis of images of cells and their surroundings obtained from a digital imaging device or system. Embodiments of the disclosed subject matter make use of a “microwell array,” which can comprise a formed, elastomeric grid of indentations or “wells.” Many, most, or all of the wells in a microwell array can contain a releasable, microfabricated element, which can be referred to as a “raft.” Embodiments of the disclosed subject matter provide a system and method for cell collection that includes computerized identification and collection of rafts with isolated single cells or a specific group or groups of cells, eliminating the need for continuous human identification and selection.

  • Publication number: 20140275765
    Abstract: A fiber optic probe assembly comprises an optical engine and a fiber optic probe. A proximal end connector comprises a self-aligning connector for connecting optical fibers of the fiber optic probe to the optical engine and an integrated fiber optic-based polarizer. A disposable cover is provided for enclosing at least a portion of a fiber optic probe assembly. The disposable cover comprises an elongated tubular housing and a sheath portion adapted to receive at least a portion of the fiber optic probe between ends of the housing. A handle is disposed on a proximal end of the housing, the handle comprising a self-tensioning device. An optical window is disposed on a distal end of the housing, the optical window adapted to provide for alignment with optical elements of the fiber optic probe.
