To ensure that the tissue structures of biological samples are easily recognizable under the electron microscope, they are ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

At school, it's often presented as a tidy double helix but scientists are revealing the varied and intricate shapes of DNA molecules. DNA is a molecule found in just about every living cell. Because ...

In the world of nanotechnology, where structures are measured in billionths of a meter, precise imaging and measurement techniques are essential. Critical Dimension Scanning Electron Microscopy ...

TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...

Traditional electron microscopy techniques include scanning electron microscopy (SEM) and transmission electron microscopy (TEM), where electrons that interact with the sample are imaged. 4 The ...

Scientists at Lawrence Berkeley National Laboratory made a big leap in their research into all things small. Within the past few months, scientists there began using what they say is the world’s most ...
