POROUS MEMBRANES WITH A POLYMER GRAFTING, METHODS AND USES THEREOF

摘要

A modified porous membrane comprising a polymer coating grafted to a porous membrane is described. A method for analyte detection from a biological sample using an immunoassay is also provided using the modified membrane, wherein the method comprises a) providing a modified porous membrane having the structure of Formula (I), b) incubating the modified porous membrane with a first biomolecule, wherein the first biomolecule binds to the modified porous membrane to form a first biomolecule bound modified porous membrane; and c) adding a biological sample comprising at least an analyte to the first biomolecule bound modified porous membrane for analyte detection by binding the analyte to the first biomolecule bound to the modified porous membrane.
