Abstract

The invention describes a multi-element array recognitive sensor, i.e. "e-nose", based on the detection of analytes (1) within nanowire/metal junctions. The contact impedance between a nanowire (6) and a metal electrode (4) changes when different molecules are adsorbed in the region of contact between the metal electrodes (4) and the nanowire (6). The impedance change of each element is different when different metal electrodes (9-12) are used, which forms the basis for a multi-element sensor made with different materials, each of which giving a different response. The recognitive sensing properties are obtained by analyzing - using appropriate software the response of the entire array and comparing it with the reference response for different analytes (1).
