Molecule of the Month: Nanowires
Nanowires conduct electrons one at a time inside biological molecules.
Exploring the Structure
Designed Silver-DNA Nanowire
Researchers in nanotechnology are using biology as inspiration and designing their own nanowires. One approach is to use DNA as the scaffold to position the electron-carrying cofactors. The structure shown here, PDB ID 7xkm, is a short piece of DNA with a base sequence that is designed to trap silver ions (gray spheres) at the center of the double helix. The goal is to be able to embed these types of nanowires into larger DNA nanostructures. To explore this structure, choose the JSMol tab above for an interactive view.
