This is interesting, and I guess I have a few questions, for someone knowlegeable out there:

Can these nanowires be fabricated on an on-chip array?

If so, how densely?

I'm assuming that they are electrically conductive, so can we create control circuitry to run them at the previously mentioned density?

Can those circuits be made bio-compatible?

If all there are true, then this might be a good upgrade for existing neural interface devices, depending on longevity.
