Biopolymer resonant tunneling with a gate voltage source

摘要

The invention provides an apparatus and method for sequencing and identifying a biopolymer. The invention provides a first electrode, a second electrode, a first gate electrode, a second gate electrode, a gate voltage source and a potential means. The gate electrodes may be ramped by a voltage source to search and determine a resonance level between the first electrode, biopolymer and second electrode. The potential means that is in electrical connection with the first electrode and the second electrode is maintained at a fixed voltage. A method of biopolymer sequencing and identification is also disclosed.
