Naked‐eye detection : The versatility of direct‐write nanolithography was combined with the unrivaled resolution and selectivity of molecular self‐assembly to show, for the first time, the molecularly mediated placement, with nanometer accuracy, of single Au nanoparticles within a plasmonic array. In doing so, a coupled plasmonic systems was created which allowed colorimetric, naked‐eye detection of protein–protein binding at extreme sensitivities.
