Abstract

FIB/SEM microscopes have proven to be indispensable tools for cryo-electron microscopy and volumetric imaging of biological specimens. These devices can be used to analyze samples at room temperature and under cryo-conditions. Equipped with automation software for both data acquisition and electron transparent lamella fabrication, FIB/SEM microscopes offer a wide range of applications and multiple workflows for obtaining volumetric information. The imaging capabilities include high-resolution serial imaging with FIB/SEM tomography (slice & view), millimeter-scale analysis with the spin mill method, array tomography and correlative microscopy with the iFLM system. Additionally, Plasma-FIB systems allow the use of up to four different ion species, which can be used to optimize milling and imaging for both cryogenic and resin-embedded samples. In this lecture, I will provide an overview of the current state of developments, applications, and the related FIB/SEM product range.
