Nanowrapper Team (IMAGE) DOE/Brookhaven National Laboratory Caption Yugang Zhang, Oleg Gang, Fang Lu, and Mingzhao Liu hold structural models of 'nanowrappers' made of gold and silver and featuring holes in the corners. The scientists synthesized these hollow, porous nanostructures through a chemical reaction and characterized them using electron microscopy and optical spectroscopy capabilities at Brookhaven Lab's Center for Functional Nanomaterials.
