Breathing a Sigh of Disease DetectionBreathing a Sigh of Disease Detection

A University of Florida professor is taking breath sampling a step further with an add-on device that touts more sensitivity and thus more accuracy in detecting chemicals, cells, and microorganisms in exhaled breath. Paul Davenport, PhD, developed the device to work in conjunction with existing breath testers, which should improve the function of the tests while also reducing costs. The device uses high frequency oscillation to apply vibratory air pressure waves to increase the concentration of substances in a breath sample. The waves are superimposed on airflow to create airway turbulence and increase gas molecule diffusion towards the mouth. Cells that line the airway, along with bacterial components, are pushed out when the patient exhales to create more concentrated substances in the sample. The technology is patent pending and available for licensing. Contact John Byatt in UFL's Office of Technology Licensing for more details.
