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.

Adaptive illumination for superresolution STED imaging at minimal light dosages. Lifetime imaging and advanced time-gating. Pulsed high-power STED lasers for best resolutions with 2D and 3D superresolution nanoscopy; Detectors with superior detection efficiency (up to 65%) Dual-color STED imaging with spectral discrimination has been shown earlier . Since, from those experiments, our STED microscope was pre-equipped for two-color operation we were able to combine lifetime and spectral separation to perform three-channel STED imaging with resolution not fundamentally limited by diffraction.

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).

YOYO-1 shows a 500-fold fluorescence enhancement upon binding to DNA. STED instruments utilize a raster-scan imaging scenario similar to a laser-scanning confocal microscope. In contrast, stochastic optical reconstruction microscopy ( STORM ), as performed using Nikon's N-STORM system, is a single-molecule approach that relies on activation of a limited subset of the overall molecular population to sequentially image and localize individual emitters on a Light-Sheet Imaging. Long time-lapse imaging of live model organisms with low phototoxicity; Ultrafast volumetric imaging of cells with lattice light-sheet microscopy; Super-Resolution Imaging in Living Cells – MoNaLISA. Smart probes.

STED images allowed checking for filament fragmentation after application of an external rotating magnetic field. The far-red fluorescent protein TagRFP657 proved suitable for STED imaging, permitting a 4-fold reduction in apparent filament diameter from 240 nm to about 60 nm.

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. 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. This adjustable, super resolution system performs four-color, live-cell 3D imaging at the nanoscale in real time. The STED microscope was selected following a multi-week, hands-on evaluation and feedback from users on both the Leica STED-3X and the Abberior easy3D STED.

Obtain cutting-edge nanoscopy results in no time with astounding image quality and resolution, while protecting your sample. In contrast to SIM and SML, imaging by STED microscopy has an inherent advantage of immediately providing a hardware-based image with improved resolution without the need for post-processing procedures, which makes it less prone to incorrect data processing and interpretation. Optimal STED imaging of a given sample always relies on the proper tuning of several acquisition parameters, including the depletion and excitation powers, and the integration time. In particular, a major limitation to the total number of photons that can be collected during STED imaging is represented by the onset of photobleaching. Imaging dendritic spines in the hippocampus in vivo is challenging because of its remote location more than 1 mm below the surface of the mouse brain.

9 Jul 2020 Stimulated emission depletion (STED) microscopy provides super-resolved images by selective deactivation of fluorophores in the outer region

Unlike PALM and STORM which are widefield imaging methods, STED microscopy is a deterministic scanning approach. It uses the non linearity of Stimulated Emission to overcome the Abbe diffraction limit. STED uses two laser beams. The first one, the excitation beam, excites the fluorescent molecules.

Fig. 1 Correlative imaging. (A) Images of the same area are acquired in different modes.The confocal and STED images are acquired in reflection, while the AFM probe reaches the sample from above, providing a three-dimensional topographical view at high resolution.

Any movement of the imaging area within the acquisition time caused by vibrations of the microscope, vital functions of the mouse such as heart beat, or pressure pulse, or thermal drift leads to distorted images. 2020-05-19 · STED imaging with this mask (2D STED) increases the lateral resolution (Fig. 1 B) but leaves axial resolution unchanged (Fig. 1 D). In our microscope, the phase mask was created by an SLM, and as such, it could be swapped to any other phase mask to change the STED confinement mode without changing the optical layout. To enhance contrast, raw 2P-STED image stacks were subjected to deconvolution (Huygens HuCore version 17.4, Scientific Volume Imaging b.v., Hilversum, The Netherlands) utilizing a theoretical PSF based on microscope parameters and classic maximum likelihood estimation (cmle) with a quality stop criterion of 0.01, automatic background estimation and a signal-to-noise ratio (SNR) of 15.

Due to their small sizes, good stability, and surface functionalization, the cell‐surface markers and subcellular structures are specifically labeled by the AIE dot bioconjugates. Remarkably, stimulated emission depletion imaging with AIE dots is achieved for the first time, and the spatial resolution is significantly enhanced to ≈95 nm.
