Patent ID: 8003397

Claim:
A method for detecting and differentiating the presence of glucose from other monosaccharides and disaccharides in a sample, the method comprising exposing a polymeric sensing fluid of a viscometric sensor device to the sample, wherein the polymeric sensing fluid comprises a polymer having an acrylic polymeric backbone with a plurality of boronic acid moieties attached, wherein the polymer comprises poly(acrylamide-ran-3-acrylamidophenylboronic acid) formed by polymerizing N-3-acrylamidophenylboronic acid and acrylamide in the presence of 2,2′-azobisisobutyronitrile, and wherein the poly(acrylamide-ran-3-acrylamidophenylboronic acid) comprises N-3-acrylamidophenylboronic acid monomer from about 0.1% to about 10% by mole of the poly(acrylamide-ran-3-acrylamidophenylboronic acid), and measuring a viscosity increase in the polymeric sensing fluid using the viscometric sensor device, thereby differentiating and detecting the presence of glucose from other monosaccharides and disaccharides in the sample.
