Stimulated Emission Depletion Microscopy (STED) Imaging below the optical diffraction limit Stimulated emission depletion microscopy (STED) is a fluorescence microscopy technique that overcomes the diffraction limited resolution of confocal microscopes.

Super-resolution microscopes overcome the limitation of confocal as well as fluorescence microscopy as they provide increased X-Y resolution beyond 200 - 250 nm. Super-resolution microscopy is expected to give new insights to ongoing research in medical science and nanotechnology by offering resolution up to 10-20 nm. Super-Resolution Microscopy (STED, SIM, (F)PALM, (d)STORM) Applications: Super-resolution microscopy enables the visualization of the smallest structures in living cells that cannot be resolved using standard widefield or confocal fluorescence microscopy. STED microscopy of sections of HER2 positive rectal adenocarcinoma revealed details in the surface and intracellular HER2 distribution that were blurred in the corresponding conventional images, demonstrating the potential of super-resolution microscopy to explore the thus far largely untapped nanoscale regime in tissues stored in biorepositories. STED provides instant super-resolved imaging with multiple channels and approaching isotropic super-resolution in three dimensions.

It creates super-resolution images by the Stimulated emission depletion microscopy (STED) is a fluorescence microscopy technique that overcomes the diffraction limited resolution of confocal microscopes. The resolution enhancement is essentially based on switching off the fluorescence of dye molecules by stimulated emission using intense laser light in the outer regions of the diffraction limited excitation focus. Instead, super-resolution by stimulated emission depletion (STED) microscopy achieving a resolution of ~50 nm laterally and ~130 nm axially has not yet frequently been applied in plant cell Super-resolution imaging techniques represent the latest wave of imaging technology and as such are bound to advance future fungal cell microscopy. A conventional light microscope is diffraction limited to a resolution of ~ 250 nm, restricting its capability to allow to accurately measure and distinguish structures in biological samples. Using STED super-resolution microscopy, we have demonstrated that three components of the human MINOS complex (mitofilin, MINOS1, and CHCHD3) form clusters that in peripheral mitochondria of several mammalian adherent cell lines exhibit a highly organized periodic spatial distribution, which appears in superresolved immunofluorescence images as a discontinuous rail-like arrangement.

[ 34 ] reported a new light-sheet microscopy possessing a high spatio-temporal resolution utilizing Bessel beams. Super-resolution structured illumination microscopy illuminates a sample with a series of sinusoidal striped patterns of high spatial frequency. This pattern is typically generated by laser light passing through a movable optical grating and projected via the objective onto the sample ( Heintzmann and Cremer, 1999 ; Gustafsson, 2000 ). We successfully employed STED super-resolution microscopy to image the subcellular distribution of several targets in various specimen including E. coli, T. brucei, S. cerevisiae, human cancer cells and bovine sperm.

Stimulated Emission Depletion (STED) Microscopy is a form of super resolution microscopy that uses a technique called spatially patterned excitation. During STED microscopy, two lasers are used on the focal plane. 2018-08-30 · Stimulated emission depletion (STED) microscopy is a powerful super-resolution microscopy technique that has achieved significant results in breaking the resolution limit and relevant applications. In principle, STED super resolution is obtained by stimulated emission partially inhibiting the spontaneous emission in the periphery of a diffraction-limited area.
