Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods ...
In the 20 th century, light microscopes relied solely on focusing light in space for the separation (=resolution) of adjacent tiny features. Either they focused the illumination light as sharply ...
Optical microscopes are still second to none when it comes to analyzing biological samples. However, their low resolution, improved only in recent years in STED microscopes, continues to be a problem.
“The resolution of the standard optical microscope is basically limited by the diffraction barrier of light, which restricts the resolution to 200–300 nm for visible light,” explains Mark Schüttpelz, ...
A team has made a major breakthrough in the field of three-dimensional (3D) imaging of large-scale biological tissues. They ...
A new type of super-resolution optical microscopy takes a high-resolution image (at right) of graphite "nanoplatelets" about 100 nanometers wide. The imaging system, called saturated transient ...
