Development and combination of various microscopic and spectroscopic techniques

13-Sep-2024 - How can molecular structures be analysed when the resolution of the techniques available is not sufficient? Researchers from the fields of physics, chemistry and medicine at Heinrich Heine University Düsseldorf (HHU) have combined and further developed various microscopic and spectroscopic ...

Frequency-domain STED microscopy for selective background noise suppression

Novel method suppresses background noise in STED microscopy selectively and effectively, with potential for integration into other dual-beam point-scanning techniques

08-Jul-2022 - Nanoscopy describes the ability to see beyond the generally accepted optical limit of 200–300 nm. Stimulated emission depletion (STED) microscopy, developed by Stefan W. Hell and Jan Wichmann in 1994, and experimentally demonstrated by Hell and Thomas Klar in 1999, is a superresolution technique ...

New microscopy method resolves fluorescent molecules with resolution at the nanometer scale

22-Mar-2021 - Scientists working with Stefan Hell at the Max Planck Institute (MPI) for Biophysical Chemistry in Göttingen and the Heidelberg-based MPI for Medical Research have developed another light microscopy method, called MINSTED, which resolves fluorescently labeled details with molecular sharpness. ...

The Nobel Prize in Chemistry 2014: Surpassing the limitations of the light microscope

Eric Betzig, Stefan W. Hell and William E. Moerner are awarded the Nobel Prize in Chemistry

08-Oct-2014 - For a long time optical microscopy was held back by a presumed limitation: that it would never obtain a better resolution than half the wavelength of light. Helped by fluorescent molecules the Nobel Laureates in Chemistry 2014 ingeniously circumvented this limitation. Their ground-breaking work ...
