Stimulated emission depletion microscopy with optical fibers
Imaging at the nanoscale and/or at remote locations holds great promise for studies in fields as disparate as the life sciences and materials sciences. One such microscopy technique, stimulated emission depletion (STED) microscopy, is one of several fluorescence based imaging techniques that offers resolution beyond the diffractionlimit. All current implementations of STED microscopy, however, ...
متن کاملSpectroscopic rationale for efficient stimulated-emission depletion microscopy fluorophores.
We report a rationale for identifying superior dyes for stimulated-emission depletion (STED) microscopy. We compared the dyes pPDI and pTDI, which displayed excellent photostability in single-molecule spectroscopy. Surprisingly, their photostability and performance in STED microscopy differed significantly. While single pTDI molecules could be visualized with excellent resolution (35 nm), pPDI ...
متن کاملStimulated Emission Depletion (STED) Microscopy: from Theory to Practice
In recent years, various methods have been proposed to increase the resolution of fluorescence microscopy beyond the diffraction limit of light. Amongst them, Stimulated Emission Depletion (STED) microscopy, which relies on a purely physical concept of fluorescence depletion could, in theory, achieve unlimited resolution independent of the wavelength of light. In this chapter, we review the fun...
متن کاملDefining the Noise-limited-resolution for Stimulated Emission Depletion Microscopy
With recent developments in microscopy, such as stimulated emission deletion (STED) microscopy, far-field imaging at resolutions better than the diffraction limit is now a commercially available technique. Here, we analyse how the interplay between shot noise, thermal noise, the saturation intensity of a fluorescent label, and the damage threshold of the sample changes the maximum resolution of...
متن کاملThree-dimensional stimulated emission depletion microscopy of nitrogen-vacancy centers in diamond using continuous-wave light.
Charged nitrogen-vacancy (NV) color centers in diamond are excellent luminescence sources for far-field fluorescence nanoscopy by stimulated emission depletion (STED). Here we show that these photostable color centers can be visualized by STED using simple continuous-wave or high repetition pulsed lasers (76 MHz) at wavelengths >700 nm for STED. Furthermore, we show that NV centers can be image...
