Abstract
A detection system for an electronic nose which allows a physicochemical classification of odors, that is to say a classification as a function of the physicochemical properties of the volatile compounds, or odorous molecules, making up these odors. This detection system comprises sensors with cross-reactivity with respect to volatile compounds, each sensor comprising a sensitive part functionalized by a receptor comprising a sequence formed by the repetition of an α-amino acid. The α-amino acid of the receptor of a sensor of a first series of sensors is hydrophilic, while the α-amino acid of the receptor of another sensor of the first series is hydrophobic, and the α-amino acids of the receptors of two sensors of a second series of sensors have isoelectric points which differ from one another by at least one pH unit.
