Growth of the oxidized nickel nanoparticles on a DNA template in aqueous solution

Oxidized nickel nanoparticles ranging from 2 to 3 nm have been grown on a DNA template. The synthesized products have been characterized by AFM and XPS. The results showed that uniformly oxidized nickel nanoparticles can be grown and assembled on a DNA template. These assembled small NiO nanostructures may have some potential application as catalysts, magnetic materials or electrochromic films. Theoretically, this synthetic method can be applied to fabricate other metals on a DNA template.
