Imaging a smell, Plasmonic-based optoelectronic nose

Orateur : Thierry LIVACHE (Directeur Scientifique d’Aryballe Technologies)

Beyond the classical lock/key-recognition-based approach in used in the bio-analytical field, an electronic tongue or nose device (eT/eN) is an assembly of non-specific sensors. Following a long story around the imaging of biological interactions of biomolecules by Surface Plasmon Resonance Imaging, we recently extended this approach to the non-specific interactions studies in gas phase giving rise to a new optical-nose generation. The signals resulting from the binding of VOCs (Volatil Organic Compounds) on an array of bioinspired receptors can be seen as 3D continuous dynamic images or movies. Finally, complex data obtained from odors are analyzed as simple images via a specific database. This flexible and straightforward approach allowed a down-scalling of the device and a new miniaturized portable and generic opto-nose Neose was recently launched by Aryballe Technologies. The translation of a smell into an image could be seen as a first step to open up the merging of the olfactory and visual senses…
