Abstract
DNA hybridization enables the three-dimensional assembly of Au nanoparticles and streptavidin (see picture). The high-density DNA-modified Au nanoparticles were stable to nonspecific binding of streptavidin. Structural and melting investigations on the assemblies showed their formation was reversible.Keywords
