Optics for Ultrafast Cameras Create New Possibilities for Imaging
  • Damaged retinas, such as the one highlighted here, could eventually be replaced by artificial ones made from 2D materials

    Ultrathin Artificial Retinas Based on 2D Materials

    Scientists report they have successfully developed and tested the world's first ultrathin artificial retina that could vastly improve existing implantable visualization technology for the blind. The flexible 2D-material-based device could...

    Modulating Photo- and Electroluminescence in Fluorescent Dye

    Controlling the excited electronic states in luminescent systems remains a challenge in the development of fluorescent and phosphorescent dyes. Now, scientists in Japan have developed a unique organic fluorophore that changes its emission color...
  • 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
  • Developing innovative solutions to tackle microbial infection

    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...
  • Piezoelectric deformable mirror PDM developed in the EU project ultraSURFACE

    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

    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...
