SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

Microscopy continues to transform the life sciences. Here are five recent breakthroughs made possible by the technique.

Electron microscopy (EM) has become an indispensable tool for investigating the nanoscale structure of a large range of materials, across physical and life sciences. It is vital for characterisation ...

The motion of whizzing electrons has been captured like never before. Researchers have developed a laser-based microscope that snaps images at attosecond — or a billionth of a billionth of a second — ...
