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

Researchers at TU Graz have proven that espresso is a favourable alternative to the highly toxic and radioactive uranyl acetate in the analysis of biological samples.

Researchers have identified a common household beverage as an effective, non-toxic substitute for the hazardous chemicals ...

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 ...

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 ...

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 ...

Since the 1950s, scientists have worked around this problem by coating samples with a thin layer of gold before imaging. While this approach made electron microscopy possible for countless discoveries ...
