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.

WebCryo-focused ion beam microscopes (cryo-FIBs) can also be used to thin protein microcrystals for microcrystal electron diffraction ( MicroED ), a technique that produces high-resolution 3D molecular structures of small chemical compounds or biological macromolecules. Cryo-FIB-SEM technology WebFigure 3: Thin section FIB sample prep for Scanning Transmission Electron Microscopy (STEM). Sample is milled from both sides to form a thin section containing the area of interest (Left). Using an in-situ manipulator, the section is removed from the sample (Right) and will be mounted to STEM sample holder for final thinning. WebThe chemically assisted ion beam etching uses the technology of ion beam milling or ion beam trimming and adds additional reactive gases close to the substrate, typically by a gas ring. This can lead to increased etching rate or higher material selectivity of the etching process. Related Systems. scia Mill 150; scia Mill 200; scia Mill 300 spectrum doctors in muskegon
