STED microscopy is one of several types of super resolution microscopy techniques that have recently been developed to bypass the diffraction limit of light microscopy to increase resolution. STED is a deterministic functional technique that exploits the non-linear response of fluorophores commonly used to label biological samples in order to achieve an improvement in resolution, that is to say STED allows for images to be taken at resolutions below the diffraction limit.

Stimulated emission depletion (STED) STED microscopy uses two laser pulses to localize fluorescence at each focal spot. 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. STED Super-resolution Microscopy Reveals Mitofilin Localized in Individual Clusters. To visualize the distribution of mitofilin in primary adult human skin fibroblasts, we decorated chemically fixed cells with a polyclonal antiserum generated against full-length human mitofilin. Abstract. Super-resolution imaging techniques represent the latest wave of imaging technology and as such are bound to advance future fungal cell microscopy.

These include stimulated emission depletion (STED) microscopy, structured illumination microscopy (SIM), and stochastic optical reconstruction microscopy (STORM)/photoactivation localization microscopy (PALM). 2018-08-30 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. Underlining the impact of super-resolution microscopy, the 2014 Nobel Prize for Chemistry was awarded jointly to Eric Betzig, Stefan W. Hell and William E. Moerner "for the of super-resolution imaging techniques, including stimulated emission depletion (STED) microscopy [7,8], photoactivated light microscopy [9], and stochastic optical reconstruction microscopy [10,11], albeit with applications mainly in life science imaging and in material research where spatial patterns of position rather than orientation were probed. Stimulated emission depletion (STED) STED microscopy uses two laser pulses to localize fluorescence at each focal spot.

STED microscopy is a diffraction-unlimited super-resolution microscopy that has attracted wide attention, given its power to achieve super-resolution images without additional data processing, thereby greatly reducing the risk of producing artifacts (Hell and Wichmann 1994; Vicidomini et al.2018). 00:00:15.17 of super-resolution fluorescence microscopy with emphasis 00:00:18.29 on STED microscopy.

High-Resolution Molecular Imaging and Its Applications in

Unfortunately, this increased optical resolution also leads to a drawback: because many fluorophores are depleted by the depletion laser, this also results in a lower signal (fewer photons) being captured by the detector.

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.

EM and STED super-resolution microscopy on the very same samples, providing high-resolution information about specific protein localisations as well as the cellular ultrastructure, and finally enabled us to perform true correlative super-resolution light and electron microscopy.
