Abstract 

This paper reports the transformation of rhombic dodecahedral gold nanoparticles through two different pathways depending on the water content. The gold nanoparticles were prepared by reducing HAuCl4 with N,N-dimethylforamide in the presence of poly(vinyl pyrrolidone) and water. Not only the concentration of PVP but also the water content has a critical role in determining the shape transformation of the gold nanocrystals. At low water content the rhombic dodecahedron is transformed into a rhombicuboctahedron to a truncated octahedron and then to an octahedron, while at higher water content the rhombic dodecahedron is transformed into a rhombicuboctahedron and then to a cube or a truncated cube and then to a cuboctahedron and to a truncated octahedron. In addition, we demonstrated cell imaging by using the truncated octahedral, rhombic dodecahedral and octahedral gold nanoparticles as a contrast agent.
