Berkeley Lab Researchers Apply Transmission Electron
Microscopy Through Unique Graphene Liquid Cell
Autumn is usually not such a great time for big special
effects movies as the summer blockbusters have faded and those for the holiday
season have not yet opened. Fall is more often the time for thoughtful films
about small subjects, which makes it perfect for the unveiling of a new movie
produced by researchers at the U.S. Department of Energy (DOE)’s Lawrence
Berkeley National Laboratory (Berkeley Lab). Through a combination of
transmission electron microscopy (TEM) and their own unique graphene liquid
cell, the researchers have recorded the three-dimensional motion of DNA
connected to gold nanocrystals. This is the first time TEM has been used for 3D
dynamic imaging of so-called soft materials.
