摘要
DNA-connected strings of gold nanoparticles are arranged to form very uniformly annular arrays having various diameters of a few micrometers by adjusting evaporation conditions as well as the concentrations of gold nanoparticles and phosphorothioate-modified oligonucleotides. The circles are formed by the dry, hole-opening mechanism rather than by the Marangoni effect. However, their sizes are very diverse and their circumferences are approaching to show single-particle thinness instead of close-packed particle cluster thickness owing to DNA-linked gold nanoparticle strands.
