Electrical Signals from DNA Nano Sequencer

Technical developments in DNA sequencing tend to have a “forward-looking” character that some might call hype.  But advances have come quickly and the most forward-looking proposes not the $1,000 genome, nor the $100 genome, but one for $10. That can be believed when seen, but researchers at the University of Washington have made a nanopore sequencer that can electrically conduct a strand of DNA through a hole that’s one-billionth of a meter in diameter, and detect the base sequence from changes in the electrical signature.  Without lasers or fluorescent tags, this could indeed be an inexpensive machine.    MORE
