OT5.180 - Development and Optimization of SPRI-based Electronic Nose for Highly Selective Detection of Volatile Organic Compounds

The development of an instrument capable of performing at a level comparable to that of the biological nose remains a scientific challenge.In the present work, we have developed and optimized a multiplexed Surface Plasmon Resonance Imaging (SPRI)-based optoelectronic nose coupled to a microarray of novel sensing materials for the sensitive and selective detection of Volatile Organic Compounds (VOCs) in the gas phase.Using pattern recognition algorithms our system is able to discriminate VOCs belonging to different chemical families, as well as VOCs differing by a single carbon.
