Description
Summary:•A surface plasmon resonance imaging-based (SPRi) nose was compared to human nose.•SPRi response to 92 odorants did not reflect solely chemical properties of odorants.•As humans, semantic properties of odors contributed to the SPRi nose responses. Artificial noses are increasingly used for both research and industrial purposes. Here, we present preliminary results on the comparison between performances of an opto-electronic nose with human perception. The used artificial device is based on surface plasmon resonance technology, consisting of an array of peptide sensors binding reversely to a large number of odorants. We first identified sources of experimental variance. Controlling for such error sources, we then found that the responses of the opto-electronic nose are not a mere reflection of the chemical space of odorants, but rather that semantic dimensions are also prominent, similar to natural olfaction. This opens new directions for the development of bio-inspired artificial noses and the choice of peptide sensors.
