A fluorescence scanning electron microscope

open access: yesUltramicroscopy, 2009
Fluorescence techniques are widely used in biological research to examine molecular localization, while electron microscopy can provide unique ultrastructural information. To date, correlative images from both fluorescence and electron microscopy have been obtained separately using two different instruments, i.e.
