Scientists continue to refine travel safety measures, and the shoe bomb sensor is one way they're doing it. University of Illinois researchers Kenneth Suslick and Hengwei Lin developed the sensor, and recently published their findings in 'The Journal of the American Chemical Society.'
Their shoe bomb sensor "can detect tiny amounts of TATP vapor, even when in concentrations as low as two parts per billion," according to Fast Company. The compound TATP (Triacetone triperoxide) is found in shoe bombs. Although there is a functional prototype, it hasn't been ordered for mass production yet.
