  • Patent number: 11136251
    Abstract: The present disclosure provides compositions, methods, and devices for sensing, detecting, and/or selectively capturing phosphate from water. An exemplary method includes: contacting a ligand or a rare earth metal complex of a ligand as described herein with an aqueous phosphate-containing medium at a pH of 5 to 12 under conditions sufficient to bind phosphate (e.g., reversibly bind phosphate). In certain embodiments, the method further includes releasing the bound phosphate by contacting the bound phosphate complex with an aqueous medium at a pH of 0 to 4 under conditions sufficient to release the bound phosphate.
    Type: Grant
    Filed: March 23, 2018
    Date of Patent: October 5, 2021
    Assignee: Regents of the University of Minnesota
    Inventors: Valerie Christine Pierre, Sylvie Lilliane Pailloux, Sheng-Yin Huang, Mandapati V. Ramakrishnam Raju
  • Patent number: 10969387
    Abstract: Compounds and complexes that can be useful as enterobactin probes not necessary are disclosed herein. Methods of detecting bacteria and/or methods of determining susceptibility of bacteria to an antibiotic using such compounds and complexes are also disclosed herein.

  • Patent number: 9194802
    Abstract: A molecular probe for the luminescent detection of nucleotides (e.g., adenosine nucleotides) is presented. In certain embodiments, the probe can readily distinguish between the three adenosine nucleotides in buffered aqueous conditions at neutral pH, a need for the direct monitoring of enzymatic reactions converting ATP to ADP or AMP. The probe is most efficient under millimolar concentrations of ATP, which are relevant to intracellular conditions. In preferred embodiments, the long luminescence lifetime of the probe readily enables time-gating experiments.
