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.

2019-07-05 · The 100x oil STED WHITE is the lens of choice for standard fixed samples and for structures close to the coverslip, with excellent performance up to 30 µm deep into the sample. It gives the highest resolution based on its numerical aperture. For live cell imaging and 2D/3D Deep STED Nanoscopy, the 93x Glyc STED WHITE is the lens of choice.

What are the most impressive advantages of STED Nanoscopy? Abstract We show that far-field fluorescence nanoscopy by stimulated emission depletion (STED) can be realized with compact off-the-shelf laser diodes, such as those used in laser pointers and DVDs. A spatial resolution of 40-50 nm is attained by pulsing a 660 nm DVD-diode.

STED nanoscopy allows one to create fluorescence interro-gation spots at nanometric scales (18,19). STED nanoscopy is based on the reversible inhibition of fluorescence emis-sion of a marker by stimulated emission. The stimulated emission is induced by the STED light at a wavelength that is typically at the red edge of the emission spectrum.
Conventional fluorescence microscopy is decisive for addressing central challenges in many areas of life Typical STED.

Stimulated emission depletion (STED) nanoscopy plays a key role in achieving sub-50 nm high spatial resolution for subcellular live-cell imaging.
Its typical single-point scanning implementation can lead to long acquisition times. In order to unleash the full spatiotemporal resolution potential of STED nanoscopy, parallelized scanning is mandatory. Here we present a dual-color STED nanoscope utilizing two orthogonally crossed

STED Microscopy has been successfully applied to biological samples. For example, it has been used to show neurofilaments in human neuroblastoma and create video-rate imaging of synaptic vesicles in a neuronal axon. Stefan Hell, who developed STED-Microscopy, won …
This constitutes a drawback for wide field imaging, since the gain in For example, stimulated emission depletion (STED) nanoscopy uses (in addition to a fluorescence excitation laser) a second, ring-shaped laser to quench Stimulated Emission Depletion Super-Resolution Imaging (STED).

We demonstrate live-cell STED microscopy of two protein species using photochromic green fluorescent proteins as markers. The reversible photoswitching of two markers is implemented so that they can be discerned with a single excitation and STED wavelength and a single detection channel. Dual-label STED microscopy is shown in living mammalian cells.
