Video Talk by Kurt Thorn: The Abbe Diffraction Experiment
This lecture describes the famous experiments of Ernst Abbe which showed how diffraction of light by a specimen (and interference with the illuminating light) gives rise to an image and how collection…Read article
Microscope Resolution: Concepts, Factors and Calculation
In microscopy, the term ‘resolution’ is used to describe the ability of a microscope to distinguish detail. In other words, this is the minimum distance at which two distinct points of a specimen can…Read article
Translation Microscopy (TRAM) for Super-Resolution Imaging
Super-resolution microscopy is transforming our understanding of biology but accessibility is limited by its technical complexity, high costs and the requirement for bespoke sample preparation. We…Read article
HyVolution – Super-Resolution Imaging with a Confocal Microscope
Since the invention of the microscope, there has been continual discussion about the possibility of showing more detailed features of specimens as compared to just magnifying them. In this article we…Read article
Video: Fluorescence is a State of Mind
How to break a fundamental law of physics and win a Nobel Prize to boot. Stefan Hell explains super-resolved fluorescence microscopy for which he shared the 2014 Nobel Prize in chemistry.Read article
A Brief History of Light Microscopy – From the Medieval Reading Stone to Super-Resolution
The history of microscopy begins in the Middle Ages. As far back as the 11th century, plano-convex lenses made of polished beryl were used in the Arab world as reading stones to magnify manuscripts.…Read article
Gated STED Microscopy with Time-gated Single-photon Avalanche Diode
The maximization of the useful (within the time gate) photon flux is then an important aspect to obtain super-resolved STED images. Here we show that by using a fast-gated single-photon avalanche…Read article
STED Nanoscopy: A Glimpse into the Future
The well-known saying of "Seeing is believing" became even more apt in biology when stimulated emission depletion (STED) nanoscopy was introduced in 1994 by the Nobel laureate S. Hell and coworkers.…Read article
Pathways to Optical STED Microscopy
STED nanoscopy has evolved to a highly versatile tool for the observation of the living cell, more and more finding its way into state-of-the-art optical imaging facilities in biomedical research…Read article
Video Talk by Daniel Axelrod: Total Internal Reflection Fluorescence (TIRF) Microscopy
Total Internal Reflection Fluorescence (TIRF) Microscopy is a technique that only illuminates dye molecules near a surface. In this video, the pioneer of TIRF Microscopy describes what this technique…Read article
GSDIM Publication List
GSDIM microscopy is a widefield super-resolution technique based on the localization of fluorophores with nanometer precision. With its help a lateral resolution of down to 20 nm can be achieved,…Read article
Super-Resolution – On a Heuristic Point of View About the Resolution of a Light Microscope
Since super-resolution has become one of the most favored methods in biomedical research, the term has become increasingly popular. Still, there is much of confusion about what is super-resolution and…Read article
Finding, Defining and Breaking the Diffraction Barrier in Microscopy – A Historical Perspective
Diffraction plays a crucial role in microscopy as it prevents the recording of arbitrarily sharp images with conventional light microscopes. Many names are connected with the notion of diffraction and…Read article
Super-Resolution Microscopy – Get Your Free e-Book for Download
Until recently, the diffraction of light had placed a fundamental limit on how far biologists could peer into cells with optical microscopes, preventing them from resolving features less than 250 nm…Read article
