Planar High-Speed Molecule Sequencer

A molecule sequencer uses a planar nanochannel for aligning molecules to flow past impedance interrogation electrodes mounted across the channel for rapid sequencing. The electrodes may be fixed to the channel walls to provide improved registration by co-fabrication with the channel. Extended channel length over normally used nanopores can provide improved control of longer molecules and allow parallel sequencers to be readily fabricated on a single substrate.
