Abstract:
:The scanning transmission electron microscope provides structural and chemical information of a specimen at atomic-scale resolution and complements conventional transmission electron microscopy techniques. Mass measurements can now be performed routinely on a wide range of molecular and supramolecular structures using elastically scattered electrons. Recent progress in the acquisition and analysis of electron energy-loss spectroscopy data indicates that the scanning transmission electron microscope is an efficient tool for mapping the chemical composition of biological samples.
