Better electron microscopy for biological samples

Hank Hogan

When it comes to seeing the very small, transmission electron microscopes can be big. They have been used to image crystalline metal samples with subangstrom resolution, far better than the hundreds of nanometers of resolution possible with standard light microscopy. But because of the nature of unstained biological samples, the transmission electron microscopy resolution for them is worse by a factor of as much as 50, and researchers have had to live with fuzziness. This phase plate helps improve contrast when imaging biological samples with transmission electron microscopy. It was...Read full article
