AbstractA disposable integrated miniaturized array of chemical sensors for analyzing concurrently a number of analytes in a fluid sample is described. Each sensor is a complete electrochemical cell consisting of its own individual reference and indicator electrodes and is selective with respect to a particular analyte in the sample.Where required, a sensor can be individually calibrated, such that each analysis can be read directly.
