However, in addition to the optimization of the microscope, luminescent … principles of STED and recent advancements in execution. It discusses the practical aspects in performing optimal STED experiment. Finally, it discusses the applications of STED nanoscopy in biological systems with special relevance to membrane biology.

The presented dual-channel STED microscope utilizes a single ﬁber laser providing a 20-MHz train of 775 nm wavelength pulses of 1.2-ns duration. This compact laser source en-ables STED on ﬂuorophores emitting in the orange to red range.

International conference on nanoscopy - En god løsning på hvordan man kan STED nanoskopi möjliggör bilddiffraktion med ett brett spektrum av fluorescerande sonder.

The widely popular class of quantum-dot molecular labels could so far not be utilized as standard fluorescent probes in STED (stimulated emission depletion) nanoscopy. This is because broad quantum-dot excitation spectra extend deeply into the spectral bands used for STED, thus compromising the transient fluorescence silencing required for attaining super-resolution.

As already mentioned in Sect. 1.2.1, STED nanoscopy is based on the idea of limiting the ability of molecules to fluoresce in the immediate vicinity of the geometric focus.

2019-08-27 · STED nanoscopy. STED nanoscopy was performed using a quad scanning STED microscope (Abberior Instruments, Göttingen, Germany) equipped with a UPlanSApo 100x/1,40 Oil objective (Olympus, Tokyo

Weuse this procedure to demonstrate four color STED imaging of platelets with ≤40 nm resolution and low crosstalk. By harnessing live-cell stimulated emission depletion (STED) nanoscopy and the fluorescent probe SiR-Actin, we show that the periodic subcortical actin Leica Microsystems Mikroskop - TCS SP8 STED.

Stefan Hell, who developed STED-Microscopy, won the 2014 Nobel Prize in Chemistry for his work.

Hell , and Elmar Schiebel Furthermore, the STED pulse is modified in such a way so that it features a zero-intensity spot that coincides with the excitation focal spot. Due to the non-linear dependence of the stimulated emission rate on the intensity of the STED beam, all the fluorophores around the focal excitation spot will be in their off state (the ground state of the fluorophores). Stimulated emission depletion (STED) microscopy is one of the techniques that make up super-resolution microscopy. It creates super-resolution images by the We demonstrate live-cell STED microscopy of two protein species using photochromic green fluorescent proteins as markers.
