The semiconducting behavior of gold nanoparticle assemblies linked by DNA is independent of the length of the DNA linker over the range of 24 to 72 base pairs (see picture; n =1–3). These studies indicate that the molecular recognition properties of DNA can be used to assemble nanoparticle‐based materials without passivating them or destroying their discrete structural and electrical properties.
