STORRS, Conn., March 9, 2009 – In a discovery that could have significant applications in medical imaging, homeland security, biological sensors and other areas, chemists have found a way to increase the luminescence efficiency of single-walled carbon nanotubes. According to University of Connecticut chemists, increasing the luminescence efficiency of carbon nanotubes could make it possible for doctors to inject patients with microscopic nanotubes to detect tumors, arterial blockages and other internal problems. Rather than relying on potentially harmful x-rays or the use of radioactive dyes, physicians could simply scan...Read full article

    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...

    Referred to as SWCNTs, these cylindrical nanostructures composed of a folded sheet of graphene can be used as near-infrared markers for small animal multiplex imaging. Emitting at different wavelengths, which can be tuned in the visible or NIR region, SWNCTs provide photostable, narrow bandwidth fluorescence in a wide chromatic variety. That enables simultaneous imaging of a large number of spectrally separated markers, through the use of global hyperspectral imaging. In addition to being used...
