  • Publication number: 20250180569
    Abstract: Described herein are nanoparticles comprising NaLnF4, wherein Ln includes all non-radioactive lanthanide elements, or NaYF4, and methods of making and using the same. The nanoparticles may optionally be modified with PEG or zwitterionic polymers containing a bisphosphonate end group, wherein the bisphosphonate end group optionally comprises an aminohexyl group. As described herein. NaLnF4 or NaYF4 nanoparticles may be used as high-sensitivity reagents for mass cytometry.

  • Patent number: 12103996
    Abstract: Element tags based on novel metal-polymer conjugates are provided for elemental analysis of analytes, including ICP-MS. A polymer backbone is functionalized to irreversibly bind metals that are selected prior to use by the user. The polymer is further functionalized to attach a linker which allows for attachment to antibodies or other affinity reagents. The polymer format allows attachment of many copies of a given isotope, which linearly improves sensitivity. The metal-polymer conjugate tags enable multiplexed assay in two formats: bulk assay, where the average biomarker distribution in the sample is diagnostic, and single cell format to distinguish a rare (for example a diseased) cell in a complex sample (for example, blood).

  • Publication number: 20200362062
    Abstract: Element tags based on novel metal-polymer conjugates are provided for elemental analysis of analytes, including ICP-MS. A polymer backbone is functionalized to irreversibly bind metals that are selected prior to use by the user. The polymer is further functionalized to attach a linker which allows for attachment to antibodies or other affinity reagents. The polymer format allows attachment of many copies of a given isotope, which linearly improves sensitivity. The metal-polymer conjugate tags enable multiplexed assay in two formats: bulk assay, where the average biomarker distribution in the sample is diagnostic, and single cell format to distinguish a rare (for example a diseased) cell in a complex sample (for example, blood).
