Abstract

Changing faces: The shape of gold nanorods can be finely tuned by controlled growth under sonication in DMF in the presence of poly(vinylpyrrolidone). Reshaping involves the formation of rods with sharp tips and strongly faceted lateral faces, and ultimately leads to perfect, single-crystal octahedrons (see images). Mechanistic considerations indicate a shape-inducing effect of the polymer through different binding interactions for the different faces. (Figure Presented)
