Previous detectors — film or charge - coupled devices — were either labor - intensive or offered limited resolution, but the direct electron detector is better on both fronts. (cen.acs.org)
«Cryo - EM has revolutionized structural biology, particularly in the last three years, with the invention of new kinds of electron detectors for the microscope,» says Michael Rossmann, a physicist and microbiologist at Purdue University in West Lafayette, Ind., and a coauthor of the Zika mapping study.

However, in 4D - STEM, the researchers use a high - speed electron detector to record where each electron scatters, from each scanned point. (sciencedaily.com)
