...Using first grape juice and then wine as their test samples, Jonquera-Jiménez and her team attached a series of synthetic membranes to a silicon chip called a microsensor. Each membrane detects a different chemical component of the liquid - components that, when combined, mark the distinct characteristics of each grape varietal. So far, the device can distinguish among four: chardonnay, Aisén, malvasia and macabeu. It can also measure the difference between a 2005 vintage and a 2007. "It should even be able to identify, say, a chardonnay regardless of whether it was grown in France...
...matter. E-noses have other, more practical uses. Osmetech, a British e-nose company, has dedicated itself to the detection of diseases. Its e-nose can sniff out six of the seven types of bacteria responsible for urinary-tract infections. Microsensor Systems of Orlando, Fla., makes a $9,800 portable device equipped with crystal sensors that can sniff out spoiling food and chemical weapons with equal ease. Caltech researchers sent one of their chips on John Glenn's space-shuttle mission last year to keep tabs on the quality of the cabin air. An adventurous Cyranose was even used...
