Super-resolution microscopy (SRM) describes any optical technique used to resolve structures beyond the diffraction-limited resolution of conventional light microscopy.

2021-03-25 · "Our microscope is the first instrument in the world to achieve 3D STED super-resolution deep inside a living animal," said leader of the research team Joerg Bewersdorf from Yale School of Medicine.

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. Stimulated emission depletion microscopy ( STED and the related techniques of ground state depletion ( GSD and saturated structured illumination ( SSIM) are referred to as ensemble focused light imaging techniques, and are based on non-linear optical effects that typically require the application of multiple high-intensity pulsed lasers with specialized modulation filters to control the excitation beam geometry (a technique commonly termed point-spread function engineering ). Stimulated Emission Depletion Super-Resolution Imaging (STED) STEDYCON allows imaging to nanoscopic scales with over 6x higher lateral resolution compared to a widefield microscope, using direct imaging without the need for reconstruction or post-processing. Superresolution microscopy using stimulated emission depletion (STED) creates sub-diffraction limit features by altering the effective point spread function of the excitation beam using a second laser that suppresses fluorescence emission from fluorophores located away from the center of excitation. You can capture cellular details and observe dynamics with resolution down to 120 nm. As a truly infinitely super-resolving technology, STED nanoscopy offers resolution down to 30 nanometers. STED provides instant super-resolved imaging with multiple channels and approaching isotropic super-resolution in three dimensions.

The incoherent superposition of azimuthally polarized beam with five-zone binary phase plate and the same beam with quadrant 0/πphase plate can yield a tightly focused doughnut spot surrounded completely and uniformly. 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 … STED microscopy has proven to be a valuable super-resolution technique for resolving objects smaller than the diffraction-limit, and Huygens leading STED deconvolution pushes this even further. All types of STED (STimulated Emission Depletion microscopy) images can be deconvolved with Huygens succesfully. Huygens unsurpassed STED deconvolution offers two-fold improvements in X, Y, and Z Multi Modality Super Resolution (SR) microscope that combined lattice SIM, 2D-STED and STOTM/PALM methods for SR, this system is designed for live-cell imaging.

Expand the capabilities of imaging with a dedicated STED instruments, or add STED capability to an existing microscope imaging system such as a spinning disk or point scanning confocal with plug and play ease, extreme stability, and acquire images with better than 40nm lateral resolution. 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.

Super-resolution imaging techniques represent the latest wave of imaging technology and as such are bound to advance future fungal cell microscopy.

These techniques rely on extremely precise control over the excitation, emission, and image acquisition of fluorescently labeled cells and tissues. Stimulated emission depletion (STED) microscopy is one of the techniques that make up super-resolution microscopy. It creates super-resolution images by the selective deactivation of fluorophores , minimizing the area of illumination at the focal point, and thus enhancing the achievable resolution for a given system.
