Computational Screening and Design of DNA-Linked Molecular Nanowires
NANO LETTERS, 11:604-608, FEB 2011

DNA can be used as a structural component in the process of making conductive polymers called nanowires. Accurate molecular models could lead to a better understanding of how to prepare these types of materials. Here we present a computational tool that allows potential DNA-linked polymer designs to be screened and evaluated. The approach involves an iterative procedure that adjusts the positions of DNA-linked monomers in order to obtain reasonable molecular geometry compatible with normal DNA conformations and with the properties of the polymer being formed. This procedure has been used to evaluate designs already reported experimentally, as well as to suggest a new design based on pyrrylene vinylene (PV) monomers.
