  • Patent number: 11262355
    Abstract: A system for measuring analyte concentrations has porous-walled nanocontainers containing multiple magnetic nanoparticles, the magnetic nanoparticles coated with a selective binder that is analyte-responsive and binds a the analyte, an indicator substance releasable from the selective binder by the analyte, or an indicator substance cleavable by the analyte, apparatus for exposing the nanocontainers to a fluid potentially containing the analyte, and magnetic spectroscopy of Brownian motion sensing apparatus for detecting agglutination of the nanoparticles or binding of analyte to the nanoparticles.
    Type: Grant
    Filed: December 9, 2019
    Date of Patent: March 1, 2022
    Assignee: THE TRUSTEES OF DARTMOUTH COLLEGE
    Inventors: John B. Weaver, Barjor Gimi, Karl Griswold

  • Patent number: 9074201
    Abstract: The present invention is a genetically engineered version of a lysozyme protein wherein the engineered enzyme exhibits enhanced antimicrobial activity, relative to the wild type enzyme, as a result of a reduced overall electrostatic charge. Such an enzyme is an attractive therapeutic candidate for treating microbial or viral infections, particularly in cases where the infection results in an accumulation of polyanion inhibitors at the site of infection. Respiratory tract infections are one example of an infection where such an enzyme might be a particularly useful drug.
