AMHERST, Mass. - Vincent Rotello, professor of chemistry at the University of Massachusetts, is working on what he calls a "molecular nose:" a way of sensing and identifying particular chemicals. Rotello''s research could eventually be used to identify bioterror agents such as anthrax or smallpox, he says, although the research team is currently working with benign substances, such as sugars and aspirin, as a way to hone the technology safely. The work also has applications in biomedicine, in creating new treatments and diagnostic techniques. The project is currently funded by a $950,000 grant from the National Institutes of Health.
