Light microscopy is a key tool that scientists use to image cells, organelles, subcellular structures, and molecules such as proteins and nucleic acids. Because visible light leaves biological ...

The invention that first enabled researchers to see clear images of living cells was the phase-contrast microscope, which won its inventor, Frits Zernike, a Nobel Prize in 1932. Prior to Zernike's ...

It is the computational processing of images that reveals the finest details of a sample placed under all kinds of different light microscopes. Even though this processing has come a long way, there ...

Although electron microscopy can already reveal details as small as one nanometer, ongoing research seeks to break through barriers limiting image quality and reducing the optical dose on the samples.

New Delhi: Dr. Padmavathi R., professor of pathology at Madras Medical College, has been working in her field for over 20 years. Her career went up, and so did her back pain. As a pathologist, her day ...

Infrared microscopy involves the examination of small samples, usually within the 10 to 100 μm range. Spatial resolution becomes a significant concern on the scale. The infrared light's relatively ...
