Rigid but flexible: Gold nanoplates with highly ordered surface dimples (see picture) are deposited in the interstices of periodically arranged silica nanoparticles. The silica nanoparticles not only act as rigid templates to form dimples or mesopores, but also provide a flexible reaction field that allows anisotropic crystal growth of gold in a simultaneously formed two-dimensional nanospace.
