Microorganisms point the way : The silica cell walls of various diatoms were covalently functionalized with DNA by using straightforward chemical procedures and then used as templates for the sequence‐specific assembly and 3D hierarchical arrangement of prefabricated DNA‐modified gold nanoparticles. The DNA was used to further direct the assembly of multiple nanoparticle layers onto the diatom templates (see picture).
