Gold‐nanoparticle‐functionalized enzymes act as “biocatalytic inks” for the generation of metallic nanowires via dip‐pen nanolithography. Deposition of nanoparticle‐modified oxidases or a phosphatase followed by development with their respective substrates and metal salts results in nanowires (see figure). This concept may be extended to the generation of other nanostructures via enzyme‐catalyzed particle growth.
