Abstract

Methods and sensors for detection and quantification of one or more analyte in a test sample are described. A response profile of an ion sensor to a control sample of a known interrogator ion is determined. The ion sensor is exposed to a test sample then to a second sample comprising the known interrogator ion, and a test sample response profile of the ion 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.
