Princeton scientists are peering into the smallest corners of matter using an exceptional collection of sophisticated microscopes — some so big they fill a room. These remarkable instruments have ...

Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), ...

Some of you probably know this already, but there’s actually more than one kind of electron microscope. In electronics work, the scanning electron microscope (SEM) is the most common. You hit ...

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 ...

It’s a problem that few of us will ever face, but if you ever have to calibrate your scanning electron microscope, you’ll need a resolution target with a high contrast under an electron beam. This ...

Researchers say the innovation, known as SmartEM, will speed scanning sevenfold and open the field of connectomics to a ...
