Gating with the pulsed 775 laser has less of an impact on your resultant image but can still give some improvement if used correctly. We combined 3D-STED microscopy and fluorescent labeling of the extracellular fluid to develop super-resolution shadow imaging (SUSHI) of brain ECS in living organotypic brain slices. SUSHI enables quantitative analysis of ECS structure and reveals dynamics on multiple scales in response to a variety of physiological stimuli. With a purely optical modulation of fluorescent behaviors, stimulated emission depletion (STED) microscopy allows for far-field imaging with a diffraction-unlimited resolution in theory.

STED microscopy is typically 11 Oct 2019 Here, we demonstrate confocal and STED microscopy with short, fluorophore‐ labeled oligonucleotides that transiently bind to complementary STED microscopy breaks Abbe's diffraction barrier. · TDE embedding preserves STED resolution along the axial plane in thick samples. · Improving resolution in the Stimulated Emission Depletion (STED) microscopy has been convincingly demonstrated for fundamental studies in cells, living tissue and organisms. Today 19 May 2020 Stimulated emission depletion (STED) microscopy is a versatile imaging method with diffraction-unlimited resolution. Here, we present a novel 8 Dec 2020 We correlate stimulated-emission-depletion microscopy of proteins and synchrotron X-ray fluorescence imaging of trace metals, both performed 8 Aug 2019 The physical idea of STED microscopy is very simple. With the Multicolour STED imaging with a single STED laser is also possible; and the Download scientific diagram | Super-resolution stimulated emission depletion ( STED) imaging in optically cleared kidney samples. All samples were stained for 9 Apr 2016 Resolution of STED microscopy is higher than confocal microscopy.

At SciLifeLab we had the latest state-of-the-art imaging equipment, including a CW-STED and a Ti-Sa STED super resolution microscope system, as well as an

Live cell imaging is possible using this laser due to its reduced phototoxic effects. Gating with the pulsed 775 laser has less of an impact on your resultant image but can still give some improvement if used correctly.

2021-03-25 · The problem is, 3D STED imaging has so far only really worked in thin samples. That’s because the laser light has a hard time getting through too much tissue to reach the molecules and excite them.

Remarkably, stimulated emission depletion imaging with AIE dots is achieved for the first time, and the spatial resolution is significantly enhanced to ≈95 nm. For single color STED imaging, SiR-tubulin or SiR-actin were added to DIV15 neurons in the BrainPhys medium at a final concentration of 1 µM during 1.5 hr at 37°C. For dual color imaging, SiR-tubulin and SiR700-actin were added to to the BrainPhys medium at 1 µM final concentration each and neurons were exposed during 1.5 hr at 37°C.

Because Nile Red can be effectively depleted using far-red depletion lasers (here λ dep = 775 nm), it can be combined with other membrane permeable labels, for example, live-cell compatible SiR-conjugates.

The first pulse is used to excite a fluorophore to its fluorescent state, and the second pulse is a modified beam used to de-excite any fluorophores surrounding the excitation focal spot.

Find Molecular Probes® fluorescence labels for simulated emission depletion (STED) imaging, useful to obtain high-resolution images in a large depth of field.

(A) Images of the same area are acquired in different modes.The confocal and STED images are acquired in reflection, while the AFM probe reaches the sample from above, providing a three-dimensional topographical view at high resolution.
