With a groundbreaking idea Stefan Hell forged ahead into the nano world. He constructed high-resolution optical microscopes that increase the resolution multiple times which was previously considered impossible. His trick: he marks the specimens to be examined with fluorescent dyes, illuminates them with a focussed laser beam and neutralises specifically the excited fluorescence with a second laser beam at the edge of the circle. Having received the Körber European Science Prize for his discoveries in 2011 , Stefan Hell has now been awarded the Nobel Prize in Chemistry. "The Körber Foundation congratulates Stefan Hell most sincerely on this distinction. For us, the second Nobel Prize for Körber Prize winners within a week shows that we have not only diverse, but also at the top truly efficient science here in Europe. Congratulations also to all the members of our committees whose expertise enables them to repeatedly nominate the best scientists in Europe for the prize," emphasises Matthias Mayer, Head of the Science Department at the Körber Foundation.
