  • Tri-color dual glucose and oxygen sensors and methods of preparing and using them
    Patent number: 10156573
    Abstract: The present disclosure relates to an optical fluorescence sensor comprising a probe for sensing glucose, an intra-reference probe, and a matrix. The present disclosure also relates to an optical fluorescence dual sensor comprising a probe for sensing glucose having two boronic acid moieties, a probe for sensing oxygen comprising modified porphyrin, an intra-reference probe that is rhodamine-based, and a matrix. The present disclosure additionally relates to methods of preparing these sensors and methods of using them.
    Type: Grant
    Filed: March 13, 2014
    Date of Patent: December 18, 2018
    Assignee: Arizona Board of Regents, a body corporate of the State of Arizona, acting for and on behalf of Arizona State University
    Inventors: Yanqing Tian, Liqiang Zhang, Fengyu Su, Deirdre Meldrum, Sean Buizer
  • Cellarium: thin-film sensor with microarray seal
    Patent number: 9410970
    Abstract: A triple sensor structured for simultaneous measurement of glucose, oxygen, and pH. The sensor components are in thin film states such as sensing films or membranes, with a glucose probe associated with emission of radiation in the blue part of the spectrum, an oxygen probe associated with radiation in red portion of the spectrum, and a pH probe—with a green portion of the spectrum. The optical probes are chemically grafted or immobilized in a suitable polymer matrix, alleviating the leaching of the probes from the matrix, improving the thin film sensing stability, and enabling the repeatable use of the same sensing films.
