Nanowrapper Evolution Images (IMAGE) DOE/Brookhaven National Laboratory Caption The 3-D structure and chemical composition characterizations of the products obtained after five minutes (a), 20 minutes (b), and one hour (c). The scanning electron microscope images (subscript 1, scale bars are 100 nanometers), reconstructed 3-D volume renderings (subscript 2), and 3-D elemental mappings (subscript 3, gold in green and silver in red) show the transformation of the silver nanocubes into gold-silver nanowrappers.
