Modulating Photo- and Electroluminescence in Fluorescent Dye
  • Light emitted by nanoparticles injected into the mammary fat pads of a live mouse is imaged through several millimeters of tissue This sequence shows how the light emitted by these laser-excited particles can be imaged through deep tissue two hours after

    Bacteria-fighting Polymers Created with Light

    Researchers from the Department of Chemistry and Warwick Medical School developed a way to synthesise large libraries of polymers, in such a way to make their screening for antimicrobial activity faster, and without the need to use sealed...
  • Dr Ajith Karunarathne examined toxic oxygen generation by retinal during blue light exposure

    How Blue Light Speeds Blindness

    Blue light from digital devices and the sun transforms vital molecules in the eye’s retina into cell killers, according to optical chemistry research at The University of Toledo (UT) in Ohio (US). The process outlined in the study leads to...

    Project ultraSURFACE: Surface finishing at high speed

    High precision and high quality, but too slow — this is how most laser processes for surface finishing can be described. In the EU research project ultraSURFACE, the Fraunhofer Institute for Laser Technology ILT in Aachen, Germany, together...

    Scientists Find Holes in Light by Tying it in Knots

    A research collaboration including theoretical physicists from the Universities of Bristol and Birmingham has found a new way of evaluating how light flows through space — by tying knots in it. Laser light may appear to be a single, tightly...
  • When one of these things is not like the other Computers are great at categorizing images based on objects within them, but theyre bad at figuring out if two objects within an image are the same or different New research helps to explain why tasks like th
  • Laser light acts as a tractor beam, trapping each particle in a vacuum

    Trapping Two Miniscule Spinning Particles

    So often in life we hear that size matters, in the world of quantum physics it really does. New research, led by the University of St Andrews and the College of Optical Sciences, University of Arizona, has led to the ability to trap two minuscule...
