Figure 3: Structure conductance control in dithiol-modified 11-mer dsDNA.

Logarithmic conductance histograms for experiments performed in (a) buffer, (b) 80% ethanol, (c) rinsing and measuring in buffer, (d) 80% ethanol, (e) rinsing and measuring in buffer again and finally (f) measuring in 80% ethanol again. Dashed lines are Gaussian fittings to find the most probable conductance. (g) Conductance values obtained upon multiple exchanges of solvent on a single sample. Error bars represent the standard deviations obtained from the fittings. The process is completely reversible over the six cycles studied.
