  • 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
