Investigation Into the Effects of Nucleotide Content on the Electrical Characteristics of DNA Plasmid Molecular Wires

In this study, we investigate the effect of nucleotide content on the conductivity of plasmid length DNA molecular wires covalently bound to high aspect-ratio gold electrodes. The DNA wires were all between 2.20-2.35μ in length (>6000bp), and contained either 39%, 53%, or 64% GC base-pairs. We compared the current-voltage (I-V) and frequency-impedance… CONTINUE READING
