17. 25-27 Finally, we have observed no measurable differences in film heights as a function of either pH (6.5 < pH > 7.5) or ionic strength (50-200 mM); both of these factors would be expected to affect our measurements, were electrostatic forces at our tip significant.

23. For example, with incomplete monolayers we have observed the formation of rows of DNA that form at positive applied potentials-a result that is consistent with duplexes nucleating at the fold of the 23 × √3 reconstruction.
