Sentence examples for by the diffraction barrier from inspiring English sources

However, conventional fluorescence microscopy methods are limited by the diffraction barrier and are unable to resolve structures smaller than ~200 nm.

STED microscopy separates features that are closer than the diffraction barrier by forcing them to fluoresce sequentially.

In all these methods, the diffraction barrier is overcome by employing a fluorophore transition between two states, typically a fluorescent on- and a non-fluorescent off-state (Hell, 2009) in order to separate neighboring features.

However, for its most popular imaging mode, fluorescence microscopy, the diffraction barrier is crumbling.

According to Professor Stefan Hell of the Max Planck Institute for Biophysical Chemistry, who was the first to break the diffraction barrier in 2000, all superresolution methods rely on the same fundamental principle.

This illustrates the diffraction barrier for conventional optical imaging.

Several approaches have been developed to break the diffraction barrier to achieve super-resolution.

In STED (Stimulated Emission Depletion) microscopy [ 36, 37], two pulsed lasers are used in tandem to break the diffraction barrier.

We have witnessed light microscopy breaking the diffraction barrier, and in the future the spatial resolution will only improve, with the development of super-resolution light microscopes.

To increase spatial resolution, these optical techniques and SPM can be combined, which then permits measurements to be made below the diffraction barrier (within the near-field zone).

One well established technique that can be used to explore nanoscale organization of membrane proteins below the diffraction barrier of visible light (~ 250 nm) is TEM.
