The DNA‐templated assembly of a protein‐functionalized 10 nm gap electrode from suitably modified gold nanoparticles on a silicon wafer substrate is reported (see Figure). Additionally, the protein‐functionalized electrode is recognized and bound selectively by a suitably modified 5 nm diameter gold nanoparticle localized in the 10 nm gap.
