Viewing the virus close up

02/04/2021

Advancing research into how viruses penetrate and act on human cells requires powerful cell imaging approaches. Soft X-ray microscopy is particularly suitable but has so far not been widely available. A pan-European research project called "Compact Cell-Imaging Device" with Heidelberg participation seeks to develop this technology for extensive application in medical research.
