Drawing microscopic patterns with electrons
Today we're looking at Electron Beam Lithography using a scanning electron microscope.
A laser (purple) is powerfully amplified by highly polished mirrors and focused on the electron beam (blue) to shift its phase and increase the cryo-EM microscope’s contrast, allowing biologists to ...

Cryo-EM imaging reveals how a molecular gate lets bulky proteins pass cell membranes intact
How large, fully folded proteins can pass through cell membranes without destroying them has long been one of the open questions in cell biology. Using cryo-electron microscopy (cryo-EM), Leonid ...
