These applications now include the structural characterization of purified macromolecules, helical filaments, two-dimensional (2D) arrays, and even whole cells. All of this became possible due to the improvements in sample preparation, which preserve a close to native environment for the macromolecules (Dubochet et al. 1981), as well as developments of the microscopes including computer-controlled data acquisition and dedicated data processing (DeRosier and Klug 1968; Crowther et al. 1970a).
