Electron Microscope Images: Nanoparticles Developed at Berkeley Lab (image) DOE/Lawrence Berkeley National Laboratory Share Print E-Mail Caption At left is a high-resolution transmission electron microscope image of a nanoparticle measuring 8 nanometers in diameter, with a 4-nanometer-thick shell. The scale bar is 5 nanometers. At right is a scanning transmission electron microscope image showing a collection of 8-nanometer nanoparticles with 8-nanometer shells (scale bar is 25 nanometers).
