Rotating Laser Enables Faster, Longer Imaging of Cells

Facebook Twitter LinkedIn Email
FREIBURG, Germany, April 20, 2022 — A microscopy method developed at the University of Freiburg is able to resolve cellular-level detail without fluorescence, enabling observations 100 to 1000× longer and 10 to 100× times faster, with almost double the resolution. The technique is called rotating coherent scattering (ROCS). It uses a rapidly rotating blue laser beam, causing lightwaves to scatter at the structures of cells to generate images. “We are exploiting several physical phenomena familiar from everyday life,” said Alexander Rohrbach, a professor at the University of Freiburg. “First,...Read full article
