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 ...

In a cramped, windowless room on the University of California, Berkeley, campus, two bespoke microscopes—each a Swiss Army ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...

Microscopy is an imaging technique that enables us to see a world that would otherwise be invisible to us. Once upon a time, visualizing cells, microbes and other entities not perceptible to the naked ...

Using a “spooky” phenomenon of quantum physics, Caltech researchers have discovered a way to double the resolution of light microscopes. In a paper appearing in the journal Nature Communications, a ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Until today, skin, brain, and all tissues of the human body were difficult to observe in detail with an optical microscope, since the contrast in the image was hindered by the high density of their ...

For centuries, scientists have used microscopes to magnify and peer into a world invisible to the naked eye. The earliest instruments were simple lens-filled tubes, the best of which revealed the ...
