Gated STED -- developing the next generation of super-resolution microscopes
Date:11/11/2011

This release is available in German.

Leica Microsystems has signed an agreement with the Max Planck Society and the German Cancer Research Center (DKFZ) for the development of the next generation of super-resolution STED (Stimulated Emission Depletion) microscopy. This gives Leica Microsystems the license to develop the new technology, called gated STED, into a commercial product and put it on the market.

Stefan Hell, Director at the Max Planck Institute for Biophysical Chemistry, has taken his idea of STED microscopy a momentous step further with gated STED: The new technology significantly improves the resolution and contrast previously attained with CW-STED (Continuous-Wave Stimulated Emission Depletion) microscopy, while distinctly reducing laser intensity. This enhances photostability as well as live cell capability, substantially extending the range of possible applications. Also, gated STED technology will considerably increase the number of issues that can be addressed with STED fluorescence correlation spectroscopy (STED-FCS). The main application of gated STED technology will be the observation of molecule movements in the membrane of living cells.

The new product of Leica Microsystems will be launched in the first half of the year 2012. Thanks to Leica Microsystems' modular concept, the Leica TCS SP5 and Leica TCS STED CW confocal systems already on the market can be upgraded with gated STED.

"We're delighted to be able to continue the provenly successful cooperation with the Max Planck Society, its technology transfer organization Max Planck Innovation and the DKFZ with this trailblazing product development," says Stefan Traeger, Vice President of Leica Microsystems' Life Science Division. "The new gated STED microscope will enable us to further strengthen our technological lead in super-resolution microscopy especially for confocal systems."
