Nanoscale electrode junctions have been selectively functionalized with specific oligonucleotide sequences using dip-pen nanolithography (see picture). These sequences direct the assembly of electrical circuits containing 20- and 30-nm-diameter DNA-modified nanoparticles so that junctions bridged by single nanoparticles can be realized. Different nanoparticle types can be directed to specific junctions on a single chip through solution-phase bottom-up assembly.
