Fast STED microscopy with continuous wave fiber lasers.
We report on fast beam-scanning stimulated-emission-depletion (STED) microscopy in the visible range using for resolution enhancement compact, low cost and turn-key continuous wave (CW) fiber lasers emitting at 592 nm. Spatial resolutions of 35 to 65 nm in the focal plane are shown for various samples including fluorescent nanoparticles, immuno-stained cells with a non-exhaustive selection of 5...
متن کاملDissecting tripartite synapses with STED microscopy.
The concept of the tripartite synapse reflects the important role that astrocytic processes are thought to play in the function and regulation of neuronal synapses in the mammalian nervous system. However, many basic aspects regarding the dynamic interplay between pre- and postsynaptic neuronal structures and their astrocytic partners remain to be explored. A major experimental hurdle has been ...
متن کاملSub-Abbe resolution: from STED microscopy to STED lithography
Commonly, in stimulated emission depletion (STED) fluorescence nanoscopy, light of a wavelength located at the red tail of the emission spectrum of the dye is used to shrink the effective fluorophore excitation volume and thus to obtain images with sub diffraction resolution. Here, we demonstrate that continuous wave (CW) STED nanoscopy is feasible using STED wavelengths located at the emission...
متن کاملSTED microscopy resolves nanoparticle assemblies
We demonstrate the ability of stimulated emission depletion (STED) microscopy, a far-field fluorescence imaging technique with diffraction-unlimited resolution, to reveal the spatial order of fluorescent nanoparticles. Unlike its confocal counterpart, here STED microscopy resolves the arrangements of densely packed 40 nm beads, supramolecular aggregates in a cell membrane, and colloidal nanopar...
متن کاملResolution scaling in STED microscopy.
We undertake a comprehensive study of the inverse square root dependence of spatial resolution on the saturation factor in stimulated emission depletion (STED) microscopy and generalize it to account for various focal depletion patterns. We used an experimental platform featuring a high quality depletion pattern which results in operation close to the optimal optical performance. Its superior i...
