Scanning transmission electron microscopy of unstained biological sections


THE scanning transmission electron microscope (STEM) has made possible the direct visualisation of single heavy atoms1 and, by exploitation of the high dark-field detection efficiency, has been used successfully for the imaging of stained and unstained biological specimens2. We report here some preliminary results which indicate that STEM can also be utilised for the imaging of unstained biological sections.
