Re: [DIYbio] Re: Question on DNA length detection via electrical methods

Actually I do mean single nucleotide differences in 0-1000 total nucleotides

Depends on what you mean by electrical method (label-free?), but yes.
The problem isn't sensing single nucleotide length differences, the
problem is sensing relevant single nucleotide length differences in
hundreds if not thousands of bases.
