You Shall Not Pass! Time-gated Detection Takes Care of Endogenous Fluorescence in Plant Research.
Yutaka Kodama is Associate Professor at the Biosciences Education Research Center, Utsunomiya University, Japan. He graduated from Saga University, Faculty of Agriculture, in 2004 and received his PhD…Read article
STED-FLCS: An Advanced Tool to Reveal Spatiotemporal Heterogeneity of Molecular Membrane Dynamics
Heterogeneous diffusion dynamics of molecules play an important role in many cellular signaling events, such as of lipids in plasma membrane bioactivity. However, these dynamics can often only be…Read article
4Pi-RESOLFT Nanoscopy
Here we apply the 4Pi scheme to RESOLFT nanoscopy using two-photon absorption for the on-switching of fluorescent proteins. We show that in this combination, the lobes are so low that low-light level,…Read article
Gated STED Microscopy with Time-gated Single-photon Avalanche Diode
The maximization of the useful (within the time gate) photon flux is then an important aspect to obtain super-resolved STED images. Here we show that by using a fast-gated single-photon avalanche…Read article
A Straightforward Approach for Gated STED-FCS to Investigate Lipid Membrane Dynamics
Recent years have seen the development of multiple technologies to investigate, with great spatial and temporal resolution, the dynamics of lipids in cellular and model membranes. One of these…Read article
Visualization of the Immunological Synapse by Dual Color Time-gated Stimulated Emission Depletion (STED) Nanoscopy
Here we illustrate the protocol for imaging by two-color STED nanoscopy the cytotoxic immune synapse of NK cells recapitulated on glass. Using this method we obtain sub-100 nm resolution of synapse…Read article
A New Filtering Technique for Removing Anti-Stokes Emission Background in Gated CW-STED Microscopy
Stimulated emission depletion (STED) microscopy is a prominent approach of super-resolution optical microscopy, which allows cellular imaging with so far unprecedented unlimited spatial resolution.…Read articleSTED Nanoscopy with Time-Gated Detection: Theoretical and Experimental Aspects
In a stimulated emission depletion (STED) microscope the region in which fluorescence markers can emit spontaneously shrinks with continued STED beam action after a singular excitation event. This…Read article
Multiple Microscopy Modes in a Single Sweep with Supercontinuum White Light
Lasers have been critical to the advancement on confocal microscopy, and the white light laser (WLL) offers particular advantages. Finessing WLL output for bioimaging is a complex task, though, and…Read article
