electronic control of dna (un) zipping

One of the major criticisms of dna-nanotech is the use of temperature controls to get the dna to fold in the right way.  The major advances have been to conquer this thermodynamics over the last year or so; still, it would be nice to move beyond having to use thermodynamics.  It will be interesting to see if the above electronic control of dna (un) zipping will generalise to all the great dna-nanotech advances like dna origami and other great things they've made dna-nanotechnology. If anything, this electronic control can add mechanical control to all the dna-nanotechnologies we already have.
