AbstractThis article provides a brief account of solution-phase methods that generate silver and gold nanostructures with well-controlled shapes. It is organized into five sections: The first section discusses the nucleation and formation of seeds from which nanostructures grow. The next two sections explain how seeds with fairly isotropic shapes can grow anisotropically into distinct morphologies. Polyol synthesis is selected as an example to illustrate this concept. Specifically, we discuss the growth of silver nanocubes (with and without truncated corners), nanowires, and triangular nanoplates. In the fourth section, we show that silver nanostructures can be transformed into hollow gold nanostructures through a galvanic replacement reaction. Examples include nanoboxes, nanocages, nanotubes (both single- and multi-walled), and nanorattles. The fifth section briefly outlines a potential medical application for gold nanocages.We conclude with some perspectives on areas for future work.

Shape-controlled gold nanostructures were successfully synthesized in an aqueous solution by a one-step, non-templated thermal reduction method through heating of a poly(vinylpyrrolidone)/HAuCl4 aqueous solution. Poly(vinylpyrrolidone) (PVP) serves as both the stabilizing surfactant and reducing agent for the controlled synthesis of gold nanostructures with different shapes. Upon adjusting the chain-length and the concentration of the PVP, decahedral, icosahedral and platelike gold nanostructures with dominating distribution were fabricated, respectively, with the ratio of terminating OH groups at the polymer to Au ions as an important experimental parameter. The results suggest that the morphology of the gold nanostructures could be tuned by this method. The successful preparation of gold nanostructures exemplifies a very facile, effective, and generic strategy for fabrication of gold nanoparticles with various shapes.
