British electronic-nose developers have found that adding a mucus layer to their e-nose improves its sniffing ability. Just like the mucus in a human nose, the synthetic mucus used on the e-nose controls the sniffing rate, thereby improving precision and accuracy, as well as length of time required for odor analysis. Some aroma identification that had been challenging for the pre-mucus e-nose, such as distinguishing milk from cream, is now being done with ease. The research team, from the University of Warwick and Leicester University, thinks the mucus-enhanced e-nose could be on sale sometime in 2009. The team is looking into health-care diagnostic uses, including for eye infections, skin diseases and urinary infections.
