Gold nanoplates mixed with spherical nanoparticles were prepared in lecithin lamellar liquid crystals containing non‐ionic surfactants as reductant. The effects of the concentrations of surfactants, reactants and salt on the formation of the nano‐products are discussed. The selective adsorption of lecithin headgroups on metal surfaces plays an important role in nanoplate formation. However, this effect is weakened by the large volume of the headgroups and only a few plates can be observed. Using biological liquid crystals as a template to synthesize the anisotropic noble metal nanoparticles will be helpful for better understanding the formation of nanostructures with controllable morphologies in biomimetic systems.
