Laterally structured hybrid assemblies composed of genetically engineered polypeptides and fused‐ring organic molecules were used to guide the assembly of gold nanoparticles in a site‐selective fashion (see image). Gold‐binding protein was covalently bonded onto a self‐assembled monolayer of preformed, π‐conjugated thiols on a Au(111) substrate by microcontact printing to produce a 2D template with submicrometer patterns. The assembly of gold nanoparticles occurred through surface recognition.
