    • 6NHCOO-5′-AGT ACT GCA GTA GCG-3′; a solution of mismatched duplexes instead contained the thiol-modified strand hybridized to a complement containing a single nucleotide substitution (5′-CGC TAC TGT AGT ACT-3′). After separate annealing, matched and mismatched duplexes were mixed to the desired % PM.

    • A duplex DNA solution was deposited on gold-mica surfaces previously mounted on a STM fluid cell. The latter contained Ag (reference) and Pt (auxiliary) electrodes connected to a biopotentiostat that independently controlled tip and surface potentials. The tips (Pt-Ir) were insulated as described in Nagahara, L.; Thundat, T.; Lindsay, S. Rev. Sci. Instrum. 1989, 60, 3128. All images were obtained in constant current mode (50 pA setpoint), and tip potential was kept 0 V vs Ag wire using the STM controller Nanoscope III. The color code is a linear gradient from black (0 nm) to white (5 nm).
