Abstract	Wormlike micelles (WLMs) are a special class of surfactants, which due to their peculiar morphology (semi-flexible polymer like), provide an exciting template for synthesis of nanoparticles. In this work, a robust method for synthesis of nanorods, assisted by the templating effect of the WLMs, as well as specific magnetic or electrical dipolar interaction between the particles, is provided. Thereby, nanorods of a variety of materials such as semiconductors, metal halides, magnetic and photovoltaics are synthesized using this method. The generality of this method is established by the use of both cationic and anionic surfactant systems. The method shows a good yield of nanorods when the viscosity of the worm-like micellar phase is reduced. It appears that spherical nanoparticles, assisted by the templating effect of the WLMs, self-assemble into chains, which fuse together by interparticle interaction to yield well formed nanorods. This establishes the method as a fairly reproducible and straight-forward method of synthesizing nanorods, albeit in certain classes of materials.
