Abstract:
1. An apparatus for detecting a biopolymer in a nanopore, comprising: (a) a first electrode; (b) a second electrode adjacent to said first electrode; (c) a nanopore adjacent to said first electrode and said second electrode and positioned to allow said biopolymer to be positioned between said first electrode and said second electrode; and (d) potential means for electrically connecting said first electrode and said second electrode for applying a ramping voltage over an energy spectrum of the biopolymer from said first electrode, through a portion of said biopolymer in said nanopore, to said second electrode to produce a signal indicative of said portion of said biopolymer; wherein ramp-time of the applied voltage is short compared to a nucleotide translocation time through the nanopore.
