Abstract
Since the discovery of their one-dimensional electronic band structure1, the leading candidate that has emerged for nanodevice applications is single-walled carbon nanotubes (SWNTs) . Here we unite their unique properties with the specific molecular-recognition features of DNA by coupling SWNTs to peptide nucleic acid (PNA, an uncharged DNA analogue2) and hybridizing these macromolecular wires with complementary DNA. Our findings provide a new, versatile means of incorporating SWNTs into larger electronic devices by recognition-based assembly, and of using SWNTs as probes in biological systems by sequence-specific attachment.
