NORMAN, Okla., Aug. 28, 2008 – Studies have shown that dogs can detect cancer by smelling certain gasses on the breath of patients, but unfortunately dogs can’t tell us exactly what gasses they smell. Intrigued by the concept of using breath analysis to detect cancer, Patrick McCann and a small group of internationally known researchers at the University of Oklahoma, are working to create a sensor to detect biomarker gases that are exhaled in the breath of a person with cancer. By using mid-infrared laser technology to help elucidate the relationship between specific gas phase biomarker molecules and cancer, McCann...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
