  • Bacteriophage-based biosensor for microbial detection
    Patent number: 9921219
    Abstract: A biosensor for detecting a microorganism in a sample includes a polymer matrix and an immobilized layer of bacteriophages on the surface of the polymer matrix, wherein interaction of the bacteriophage with the microorganism causes a detectable physicochemical change in the polymer matrix. A method of detecting a microorganism in a sample using the biosensor includes the steps of contacting the sample with the biosensor; allowing the bacteriophage to bind to the microorganism in the sample; and detecting a physicochemical change in the polymer matrix, the change being indicative of the presence of the microorganism.
    Type: Grant
    Filed: August 27, 2015
    Date of Patent: March 20, 2018
    Inventors: Anastasia Elias, Dominic Sauvageau, Zachary Storms, Chanchan Wang, Preetam Anbukarasu, Diana Martinez-Tobon
  • Adhesives derived from agricultural proteins
    Patent number: 9522515
    Abstract: The invention is directed to adhesives derived from animal or plant proteins, particularly canola and spent hen proteins. The adhesives are prepared by extracting the proteins by pH shifting; and either treating the extracted proteins with urea or sodium dodecyl sulfate, or polymerizing the proteins to form a protein-polymer conjugate. The invention is also directed to a wood based product comprising pieces of wood based material joined or consolidated with the adhesives.
