Fiber Optic ‘Wrench’ Twists, Turns Tiny Particles

Facebook X LinkedIn Email
ARLINGTON, Texas, Dec. 3, 2012 — The fiber optic equivalent of the world’s smallest wrench, dubbed the fiber optic spanner, can precisely twist and turn microscale objects in any direction and along any axis without moving any optical component. Developed at The University of Texas at Arlington, this new twist on controlling the incredibly small will allow scientists to manipulate single cells for cancer research, to twist and untwist individual strands of DNA, and to perform many other functions where microscopic precision is essential. Fiber optically trapped and rotated human smooth muscle cell in the...Read full article

    optical component
    One or more optical elements – typically cemented together - in an optical system that are treated as a single group; e.g., a beamsplitter, or a cemented doublet or triplet.
    optical tweezers
    Optical tweezers refer to a scientific instrument that uses the pressure of laser light to trap and manipulate microscopic objects, such as particles or biological cells, in three dimensions. This technique relies on the momentum transfer of photons from the laser beam to the trapped objects, creating a stable trapping potential. Optical tweezers are widely used in physics, biology, and nanotechnology for studying and manipulating tiny structures at the microscale and nanoscale levels. Key...
    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...
