A seed‐mediated growth approach to improved monodispersity of nanoparticles that involves controlling nucleation and growth in solution is presented. Using this approach, spheroidal and rod‐like gold particles (see Figure) could be prepared in the presence of a rod‐like micellar template. The aspect ratio of the particles could be varied from 1 to 10 by varying the ratio of preformed seed to metal salt.
