Mimics of mammalian olfaction have enabled the identification of many types of odorants in a variety of areas, including food, pharmaceuticals, security, space exploration, and disease diagnosis. Artificial olfactory systems have been developed to rapidly and sensitively identify vapor phase molecules to non-invasively, inexpensively and portably monitor environmental conditions. Although the electronic nose has shown excellent characteristics, there are crucial hurdles to increase the number of cross-responsive receptors in order to improve its performance. A phage-based 3rd generation sensor is called selective electronic noses because they add selectivity as a way to overcome the performance-enhancing paradigm of typical electronic nose. The addition of selectivity allows higher performance to be achieved in a smaller number of sensing units instead of giving up the excessively wide versatility of second-generation sensors. |
