New Cell-based Sensors Sniff Out Danger Like Bloodhounds, University of Maryland Study

ScienceDaily (May 7, 2008) — A small, unmanned vehicle makes its way down the road ahead of a military convoy. Suddenly it stops and relays a warning to the convoy commander. The presence of a deadly improvised explosive device, or IED, has been detected by sophisticated new sensor technology incorporating living olfactory cells on microchips mounted on the unmanned vehicle. The IED is safely dismantled and lives are saved.
