Abstract

The present invention relates to a sensor device and to a method for detecting the introduction of or changes in a chemical, biological or physical stimulus of interest in a localised environment, in particular to a sensor device and method for detecting the presence of or changes in chemical stimuli in a liquid or gas phase analyte (e.g. a microanalyte). The device compensates for fluctuations in the ambient environment.
