Regioselective Deposition of Metals on Seeds within a Polymer Matrix.

Liliang Huang, Bo Shen, Haixin Lin, Jiahong Shen, Liban Jibril, Cindy Y Zheng, Chris Wolverton, Chad A Mirkin,

We use scanning probe block copolymer lithography in a two-step sequential manner to explore the deposition of secondary metals on nanoparticle seeds. When single element nanoparticles (Au, Ag, Cu, Co, or Ni) were used as seeds, both heterogeneous and homogeneous growth occurred, as rationalized using the thermodynamic concepts of bond ...

Confined Growth of DNA-Assembled Superlattice Films.

Cindy Y Zheng, Yudong Yao, Junjing Deng, Soenke Seifert, Alexa M Wong, Byeongdu Lee, Chad A Mirkin,

We study the assembly of DNA-functionalized nanocubes under lateral confinement in microscale square trenches on a DNA-functionalized substrate. Microfocus small-angle X-ray scattering (SAXS) and scanning electron microscopy (SEM) are used to characterize the superlattices (SLs). The results indicate that nanocubes form simple-cubic SLs with square-prism morphology and a (100) out-of-plane ... Read more >>
