High-angle annular dark-field imaging
WebDark field imaging (b, d, and f) clearly reveals the Au NPs as much brighter individual spots. While corresponding dark spots might be found in the same location in the bright field images, it is difficult to differentiate them from biological or stain artifacts of similar size that are also present. Web12 de abr. de 2024 · Bright field, annular dark field (ADF), and high-angle annular dark field (HAADF) STEM imaging are primarily used for sample navigation and feature size measurement. STEM images up to one gigapixel can be acquired quickly (up to 10 Mpixels/sec) with the integrated scintillator-based bright field and ADF/HAADF detectors.
