22_04i/2012Self-Assembly: Oriented Assembly of Gold Nanorods on the Single-Particle Level (Adv. Funct. Mater. 4/2012)

Aligning shape-anisotropic nano-objects is a heavily studied topic. On page 702, Heiko Wolf and coworkers demonstrate the oriented assembly of gold nanorods with single-particle resolution. Assembly is achieved from a dense phase of nanorods at the meniscus of an aqueous suspension through capillary forces. The parallel alignment of arrayed gold nanorods becomes evident from their characteristic plasmon colors (red, green) when observed through a polarizer.
