Elemental composition control of gold-titania nanocomposites by site-specific mineralization using artificial peptides and DNA

Abstract

Biomineralization allows for crystal structure, size, and morphology control over inorganic compounds, but precipitation at random compositions hinders the construction of complex nanostructures. Here, the elemental composition of a gold-titania nanocomposite photocatalyst is controlled through two inorganic precipitating peptides bound to DNA.
