Patent number: 8758584Abstract: Systems and methods are provided for detecting the presence of an analyte in a sample. A solid state electrochemical sensor can include a redox active moiety having an oxidation and/or reduction potential that is sensitive to the presence of an analyte immobilized over a surface of a working electrode. A redox active moiety having an oxidation and/or reduction potential that is insensitive to the presence of the analyte can be used for reference. Voltammetric measurements made using such systems can accurately determine the presence and/or concentration of the analyte in the sample. The solid state electrochemical sensor can be robust and not require calibration or re-calibration.Type: GrantFiled: December 16, 2011Date of Patent: June 24, 2014Assignee: Sensor Innovations, Inc.Inventors: Carolyn R. Kahn, Elicia Wong, James A. Wilkins, Vern Norviel

Patent number: 8506779Abstract: Described herein are substrates, sensors and systems related to measuring the concentration of an analyte such as hydrogen ion in a sample. Redox active moieties whose reduction and/or oxidation potentials are sensitive to the presence of an analyte are immobilized onto a surface of an electrode. Immobilized redox active moieties whose reduction and/or oxidation potential are insensitive to the analyte can be used for reference. Voltammetric measurements made using such modified surfaces can accurately determine the presence and/or concentrations of analytes in a sample of interest. The electrochemical sensors of the invention are robust and can be made so as not to require calibration or recalibration.Type: GrantFiled: September 22, 2011Date of Patent: August 13, 2013Assignee: Sensor Innovations, Inc.Inventors: Carolyn R. Kahn, Elicia Wong, Vern Norviel

Patent number: 8197650Abstract: Described herein are substrates, sensors and systems related to measuring the concentration of an analyte such as hydrogen ion in a sample. Redox active moieties whose reduction and/or oxidation potentials are sensitive to the presence of an analyte are immobilized onto a silicon surface. Immobilized redox active moieties whose reduction and/or oxidation potential are insensitive to the analyte can be used for reference. Voltammetric measurements made using such modified silicon surfaces can accurately determine the presence and/or concentrations of analytes in a sample of interest. The silicon electrochemical sensors of the invention are robust and can be made so as not to require calibration or re-calibration.Type: GrantFiled: March 14, 2008Date of Patent: June 12, 2012Assignee: Sensor Innovations, Inc.Inventors: Carolyn R.
