Ion beam thinning

Weba radically different approach for thinning frozen-hydrated biolo-gical specimens: FIB milling. FIB instruments are commonly used in materials science to shape specimens for a variety of applications. The specimen is maintained in a vacuum and, when irradiated by the focused beam of ions (typically gallium; Ga+), thinning occurs through the process WebFocused ion beam tomography is proposed to image and assess the detailed three-dimensional (3D) ultrastructure of single bacterial cells. By iteratively removing slices of thickness in the order of 10 nm, high magnification 2D images can be acquired by scanning electron microscopy at single-digit nanometer resolution.
