We have observed novel formation of differently shaped three-dimensional aggregates among hydrophobic gold nanospheres, nanorods, and nanoboncs Gold nanobones preferentially formed spherical assemblies of 100-nm scale In the case of gold nanorods, the shapes of assemblies were profoundly affected by the aspect ratios, changing from spherical to bundlelike structure
