Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van ...

This scanning electron microscopy image captures the moment where degranulating mast cells (pseudo-colored in sepia) attract and start to incorporate living neutrophils (pseudo-colored in cyan ...

These yellow spheres are Streptococcus pyogenese bacteria bound to a human neutrophil – a key part of the immune system. Streptococcus pyogenese is the bacterium that causes strep throat in humans.

Scanning electron microscopy (SEM) is an advanced analytical tool that massively outstrips the capabilities of traditional light microscopy. Using visible wavelengths of light on the 400 – 700 ...

This scanning electron microscopy image captures the moment where degranulating mast cells (pseudo-colored in sepia) attract and start to incorporate living neutrophils (pseudo-colored in cyan ...

A new scanning transmission electron microscope (STEM) technique that modulates the electron beam in response to the scattering rate allows images to be formed with the fewest electrons possible. The ...
