Patent number: 11892386Abstract: An apparatus comprises a housing defining a chamber that has a liquid disposed therein, and a sensor submerged in the liquid. The sensor comprises a porous conductive film on a substrate, and the film comprises chemiresistive semiconducting metal oxide structures. The sensor also comprises an electrode pair operably connected to the porous conductive film for generating electric current in the film and for detecting a change in an electrical property of the film. The apparatus can be used to detect, identify, and quantify ions and molecules in a liquid sample. Molecules and ions, in a liquid sample, that interact with the porous conductive film can cause a change in an electrical property of the film. The change in electrical property of the film can be correlated with the presence and amount of the molecules or ions.Type: GrantFiled: August 26, 2021Date of Patent: February 6, 2024Assignee: Nanohmics, Inc.Inventors: Steve M Savoy, Elzbieta A Ledwosinska, Jeremy J John, Kyle W Hoover, Daniel R Mitchell, Chris W Mann, Alexander P Greis

Patent number: 10386351Abstract: Methods and sensors for detection and quantification of one or more analyte in a test sample are described. A response profile of a gas sensor to a control sample of a known interrogator gas is determined. The gas sensor is exposed to a test sample then to a second sample comprising the known interrogator gas, and a test sample response profile of the gas sensor is determined. One or more test sample sensor response profiles are compared with one or more control sensor response profiles for detecting, identifying, and quantifying one or more analytes in the test sample.Type: GrantFiled: December 7, 2016Date of Patent: August 20, 2019Assignee: NANOHMICS, INC.Inventors: Steve M.

Publication number: 20170343538Abstract: Methods and sensors for the detection, identification, and quantification of one or more gas species, including volatile organic compounds, in a test sample are described. Methods employ gas sensors comprising a diffusion matrix present on the sensor surface. A gas analyte in a test sample diffuses through the matrix and is detected upon interaction of the analyte with the sensor. A response profile of a gas sensor to a gas analyte in the test sample is compared to a control gas sensor response profile determined in a similar manner for a known gas species. Comparisons of test sample and control sample sensor response profiles enable detection, identification, and quantification of a gas species analyte in a test sample.Type: ApplicationFiled: December 7, 2016Publication date: November 30, 2017Applicant: Nanohmics, Inc.Inventors: Steve M.
