Optical Trap Holds Viruses

Facebook X LinkedIn Email
BARCELONA, Spain, Oct. 22, 2009 – A Spain-Canada research collaboration has developed a new method to gently trap, manipulate and study tiny, active objects as minuscule as viruses without inflicting any damage. The partnership between Institute of Photonic Sciences (ICFO) group leader Dr. Romain Quidant and University of Victoria (UVic) engineering professor Dr. Reuven Gordon uses a new approach to establish optical trapping technology. The team demonstrated that it is possible to use the force of light to hold and manipulate 50-nm particles – 2000 times smaller than the width of a human hair – something previously...Read full article

    Glossary
    cell
    1. A single unit in a device for changing radiant energy to electrical energy or for controlling current flow in a circuit. 2. A single unit in a device whose resistance varies with radiant energy. 3. A single unit of a battery, primary or secondary, for converting chemical energy into electrical energy. 4. A simple unit of storage in a computer. 5. A limited region of space. 6. Part of a lens barrel holding one or more lenses.
    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    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...
