Has anyone looked into using cDNA to sequence some of the major olfactory receptors expressed in animals with a keen sense of smell. Eg. Compare cDNA from the olfactory organs with that from other cells taken within-sample from the same animals. Over several animals, this would presumably give you a cDNA library specific to olfactory function. (These could then be downregulated using siRNA to assess function, but more generally, once receptors are sequenced, if one could express them in a sort of ELIZA style array, could one then develop an array sensor that would react (creating a pattern of color changes) with aromatic chemicals - allowing for potential pattern recognition (versus a control library) - and thereby potentially creating an "artificial nose" ? Has this sort of approach (eg. a sensor array using actual olfactory-receptor molecules) been tried ? —Preceding unsigned comment added by 203.45.58.46 ( talk) 16:53, 20 March 2010 (UTC)
Have any of the available technologies reached the level of cost, durability, and sensitivity required for use in trapping and fishing? For example, longline fishing has been widely criticized for the capture of sea turtles and other prohibited species, which might be automatically released when their blood is detected. A current proposal to prohibit trapping is on the ballot in Montana, [1] which might be unnecessary if a trap could be set to snap only if the scent of a target species is detected.
