  • Publication number: 20220016630
    Abstract: A microfluidic detection system for micrometer-sized entities, such as biological cells, includes a detector component incorporating a plate with a plurality of opening, the plate separating two chambers, one in communication with a fluid source containing target entities bound to magnetic beads. The openings are sized to always permit passage of the magnetic beads therethrough into a lower one of the chambers and are further sized to always prevent passage of the target entities from the upper one of the chambers. The detector component further includes a magnet positioned to pull unbound magnetic beads through the openings and to capture target entities bound to magnetic beads on the surface of the plate. In a further feature, the microfluidic detection system is configured to pass target molecules through the plate to be bound to a functionalized surface of the lower chamber.

  • Publication number: 20210393786
    Abstract: Disclosed herein is a small molecule targeted drug conjugate for anti-influenza chemotherapy and immunotherapy. The disclosed drug conjugate may form an adaptor to recruit additional CAR T cells or other immune cells for precise elimination of influenza virus-infected cells in a subject. Concurrently administered antibodies or pre-existing immunity in influenza-virus infected subject works well with the targeted conjugate to eliminate virus infected cells, saving valuable time for rescuing late stage patients.

  • Patent number: 11141494
    Abstract: Neurokinin-1 (NK-1) receptor-binding agent delivery conjugates, compositions comprising NK-1 receptor-binding agent delivery conjugates, and methods for making and administering NK-1 receptor-binding agent delivery conjugates are provided. A conjugate may include an NK-1 receptor-binding moiety, a linker group containing at least one linker selected from the group of a releasable linker and a spacer linker, and an active agent linked to the linker group. The active agent may be selected from the group of fluorophore-containing compounds, radionuclide-containing compounds, and therapeutic agents for treatment of tumor cells characterized by over-expression of the NK-1 receptor.

  • Publication number: 20210283227
    Abstract: Disclosed herein includes a drug delivery system comprising at least one peptide and a targeting ligand for bone fracture and/or for bone healing. Some embodiments include a peptide delivery system comprising at least an acidic, basic, hydrophilic, hydrophobic or neutral peptide linked to an acidic peptide or nonpeptidic polyanion for use in targeting the aforementioned attached peptide to a bone fracture surface. In some embodiments, a conjugated peptide expresses an anabolic function that acts through PTH receptor 1, and various formats of targeting ligands guide the drug to raw hydroxyapatite.
