Physicists introduce phase contrast to electron microscopy, delivering sharper images of our body's tiniest proteins
Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside ...
Stretching protein samples in all directions pulls molecules farther apart, allowing them to be visualized using only light ...

In 1931, electromagnetic lenses helped scientists see a world ordinary microscopes could not reach
In 1931, physicists Knoll and Ruska unveiled the first electron microscope, revolutionizing science by using magnetic lenses ...
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 ...
