  • Patent number: 11767468
    Abstract: Optical tags provide a way to identify assets quickly and unambiguously, an application relevant to anti-counterfeiting and protection of valuable resources or information. The present invention is directed to a tag fluorophore that encodes multilayer complexity in a family of heterometallic rare-earth metal-organic frameworks (RE-MOFs) based on highly connected polynuclear clusters and carboxylic acid-based linkers. Both overt (visible) and covert (near infrared, NIR) properties with concomitant multi-emissive spectra and tunable luminescence lifetimes impart both intricacy and security. Tag authentication can be validated with a variety of orthogonal detection methodologies. The relationships between structure, composition, and optical properties of the family of RE-MOFs can be used to create a large library of rationally designed, highly complex, difficult to counterfeit optical tags.

  • Patent number: 11644462
    Abstract: Metal-organic frameworks (MOFs) comprising amines on the organic linker can be used for cell targeting. In particular, primary amine groups represent one of the most versatile chemical moieties for conjugation to biologically relevant molecules, including antibodies and enzymes. Different chemical conjugation schemes can be used to conjugate biological molecules to the amino functionality on the organic linker. For example, carbodiimide chemistry can be used to link a primary amine to available carboxyl groups on the protein. For example, sulfhydryl crosslinking chemistry can be used via Traut's reagent scheme. As a demonstration of the invention, the ability of EpCAM antibody-targeted MOFs to bind to a human epithelial cell line (A549), a common target for imaging studies, was confirmed with confocal microscopy.

  • Publication number: 20230115755
    Abstract: A rapid and facile design strategy to create a highly complex optical tag with programmable, multimodal photoluminescent properties is described. This is achieved via intrinsic and biomolecule-fluorophore hidden signatures. As a first covert feature of the tag, an intricate novel heterometallic near-infrared (NIR) emitting mesoporous metal-organic framework (MOF) was synthesized comprising homometallic hexanuclear clusters based on Nd and Yb. To generate controlled, multimodal, and tailorable emission with difficult to counterfeit features, the NIR emissive MOF was post-synthetically modified via a fluorescent biomolecule labeling design strategy. The surface attachment of several distinct fluorophores, including the simultaneous attachment of up to three distinct fluorescently labeled DNA oligos was demonstrated, with excitation and emission properties across the visible spectrum (480-800 nm).
