Recently, arrays of many different detector molecules have been applied in so called [[electronic nose]] devices, where the pattern of response from the detectors is used to fingerprint a substance.<ref>{{cite web|title=UCSB sensor sniffs explosives through microfluidics, might replace Rover at the airport (video) |url=http://www.microfluidicsolutions.com/apps/blog/show/20808263-ucsb-sensor-sniffs-explosives-through-microfluidics-might-replace-rover-at-the-airport-video- |publisher=Microfluidic Solutions |date=8 December 2012 |archive-url=https://web.archive.org/web/20140704002927/http://www.microfluidicsolutions.com/apps/blog/show/20808263-ucsb-sensor-sniffs-explosives-through-microfluidics-might-replace-rover-at-the-airport-video- |archive-date=4 July 2014}}</ref> In the [[Wasp Hound]] odor-detector, the mechanical element is a video camera and the biological element is five parasitic wasps who have been conditioned to swarm in response to the presence of a specific chemical.<ref name=scicentr>{{cite web|title=Wasp Hound |url=http://www.sciencentral.com/articles/view.php3?article_id=218392717 |publisher=Science Central |access-date=23 February 2011 |archive-url=https://web.archive.org/web/20110716014856/http://www.sciencentral.com/articles/view.php3?article_id=218392717 |archive-date=16 July 2011 }}</ref> Current commercial electronic noses, however, do not use biological elements.
