...cancer-related protein or a plastic explosive. When that molecule sticks to it, the cantilever bends and the frequency of its vibration changes, which can be measured by bouncing a laser beam off its surface. Thundat and his team are only months from completing an exquisitely sensitive handheld detector that will suck in air and search for a variety of explosives. Since the cantilever sensors are carved out with the same technology used to build computer chips, the detector should ultimately cost only tens of dollars. In airports today the only machine as sensitive--the mass spectrometer--is too large...
...cancer. He and his team are now building arrays to detect markers for other cancers, heart disease and even mutant genes. In his spare time, Thundat is trying to figure out how to make his sensors more robust and discerning than they are, hoping to deploy them as cheap detectors of land mines, which cripple and kill thousands of people every year in war-ravaged nations like Angola. "We have a long way to go," he acknowledges. "Right now my friends tell me they wouldn't walk behind me and my detector in a minefield." If Thundat's track record...
