The synthesis of ordered nanomaterials is one of the key points in the development of novel nanotechnologies. For this purpose, simple routes to prepare building nanoblocks and their self-assembly is of special importance in the bottom-up approach. One of the most extensively studied ways to obtain nanoparticles is the microemulsion technique. In this method, small quantities of water are added to a solution  of surfactant/oil; the resulting mixture is known as a water-inoil microemulsion. If a metal precursor is contained within the water droplets, the addition of a reducing agent can result in the formation of metal particles inside these aqueous nanoreactors.One of the most extensively studied ways to obtain nanoparticles is the microemulsion technique.
