You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, ...

Using light to measure ever-smaller objects has been central to progress in many scientific disciplines for centuries. As far back as 1873, German physicist Ernst Abbe proved that light diffraction ...

Researchers from Regensburg and Birmingham have overcome a fundamental limitation of optical microscopy. With the help of ...

This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...

Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes. Using a "spooky" phenomenon of quantum physics, Caltech researchers ...

Electron microscopy has become a vital tool in structural biology, enabling researchers to visualize biological macromolecules at near-atomic resolution. Recent advances have transformed it from a low ...

Researchers from the labs of Professors Vinayak Dravid and Omar Farha developed a high-resolution approach to map ...

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...
