  • Affordable electrochemical detection of environmental contaminants
    Patent number: 10274451
    Abstract: This work provides an affordable approach for detecting environmental contaminants (e.g., arsenic in groundwater). Electro-chemical analysis of a sample is performed using a disposable three-electrode sensor that can be connected to an electrochemical analyzer (which is not disposable). The disposable sensor has a sample chamber to admit a liquid sample. The sensor includes a substrate disposed within the sample chamber that includes at least one conditioning reagent to condition the sample for electrochemical analysis. Analysis results can be displayed via a mobile device application.
    Type: Grant
