STED Microscopy (Main article STED microscopy) Within the STED microscopy (STimulated Emission Depletion microscopy) a fluorescent dye molecule is driven between its electronic ground state and its excited state while sending out fluorescence photons. This is the standard operation mode in fluorescence microscopy and depicts state A. Since STED microscopy is a far-field technique, in principle, the same sample preparation as for conventional confocal microscopy may be utilized. The increased resolution, however, requires additional precautions to ensure the structural preservation of the specimen. We present robust protocols to generate test samples for STED microscopy. Nonetheless, the light intensity required for super-resolution fluorescence microscopy is much higher than conventional microscopy, which leads to photodegradation of fluorescent dye molecules. As the spatial resolution of STED imaging correlates with an increase in STED light intensity, photodegradation of fluorescent dyes becomes a serious issue.

SR microscopy has been ground-breaking for the biomedical research Sep 23, 2008 Because a typical STED microscope can be operated as an ordinary scanning ( confocal) microscope, long-time temperature controls and 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 Stimulated emission depletion (STED) microscopy is one of the techniques that make up super-resolution microscopy.

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.

A mode of STED microscopy, known as two-photon excitation STED, enables imaging in thicker tissue samples such as brain slices. In one of the first uses of this technique, the vesicles of caveolae Stimulated Emission Depletion Microscopy (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.

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. Stimulated Emission Depletion (STED) microscopy is a fluorescence microscopy super-resolution technique that is able to circumvent the optical diffraction limit.
