Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented ...

Stretching protein samples in all directions pulls molecules farther apart, allowing them to be visualized using only light ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

Transmission electron microscopy is a general type of electron microscopy that generates an image of the internal structure of a thin sample using a beam of electrons to achieve much higher spatial ...

Werner Heisenberg's famous uncertainty principle describes one of the most intriguing features of quantum physics: certain pairs of physical quantities describing a particle, such as position and ...

Abstract: Microscopy imaging, including fluorescence micro scopy and electron microscopy, has taken a prominent role in life science research and medicine due to its ability to investigate the 3D ...

Scientists captured malaria's invasion structure in atomic detail, revealing how it actively reshapes red blood cell ...

A computer-assisted design schematic showing how an electron beam is routed within a microscope. After going through the sample, it crosses a bright cyan beam representing the laser beam. A schematic ...

Although both a SEM and a TEM are electron microscopes, their working principles and images are very different. Whereas an SEM uses secondary electrons ejected after bombarding a sample’s surface with ...
