Abstract
In this study we attempted to add new functionalities to piezoelectric sensors based e-nose by modification with gold nanoparticles (GNPs) bearing short peptide moieties. The modified piezoelectric sensors have been tested for model water solutions of aromas as isopentyl acetate, etylacetate, cis-3-hexen-1-ol and terpinen-4-ol. Principal component analysis of the data, compared with data obtained using a porphyrin based electronic nose demonstrated that this approach can be useful for the development of a new type of piezoelectric sensors for e-nose.
