  • Biological membrane-based sensor
    Patent number: 11577248
    Abstract: A biosensor detector device is disclosed suitable for use in measuring membrane fluidity or membrane permeability. The biosensor detector device is formed of a solid substrate having a lipid bilayer compatible surface, a multi-lamellar lipid membrane structure derived from a biological cell and localized on the lipid bilayer compatible surface, an aqueous layer interposed between each lipid bilayer of the multi-lamellar lipid membrane structure. The biological membrane is derived from human red blood cells and localized on the lipid bilayer compatible surface. An electrode forming all or part of the lipid bilayer compatible surface may be used to detect disruptions in the multi-lamellar lipid membrane structure and hemolytic activity in a test sample.
    Type: Grant

    Date of Patent: February 14, 2023
    Assignee: McMaster University
    Inventors: Maikel Rheinstadter, Sebastian Himbert, Richard Alsop, Jose Moran-Mirabal, Sokunthearath Saem, Dawn Bowdish
