8_15b/2012DNA–Gold Conjugates: Formation of 1D and 2D Gold Nanoparticle Arrays by Divalent DNA–Gold Nanoparticle Conjugates (Small 15/2012)

Tetragonal lattice-like 2D gold nanoparticle (AuNP) arrays are constructed by an assortment of Holliday junction-forming divalent DNA–AuNP conjugates by Y. Ohya and co-workers on page 2335. The divalent DNA–AuNP conjugate with a single-stranded DNA attached at diametrically opposed polar positions is prepared utilizing high replacement reactivity of the polar singularities of an AuNP coated with a self-assembled monolayer consisting of a binary mixture of hydrophilic thiol compounds.
