Abstract

Gold nanorods have been prepared in aqueous solution using a seed-mediated growth approach in the presence of surfactant. We observe the formation of liquid crystalline phases in concentrated solutions of high aspect ratio (13-18) gold nanorods by polarizing microscopy, transmission electron microscopy, and small angle x-ray scattering. These phases, which are stable up to 200°C, exhibit concentration-dependent orientational order.
