Researchers have used an electron microscope to produce and witness a chemical reaction induced by visible light in a nanocube of palladium roughly the size of a cold virus. This technique, which melds the resolution of electron microscopy with the color of light microscopy, could someday be used to study almost any interaction of light and matter with a resolution of about 2 nanometers, even those that occur in living cells.
