    For Detailed Instructions please see the GDB Announcement.



  • A nanopore is a nano-scale hole. In its devices, Oxford Nanopore passes an ionic current through nanopores and measures the changes in current as biological molecules pass through the nanopore or near it. The information about the change in current can be used to identify that molecule.

    Holes can be created by proteins puncturing membranes (biological nanopores) or in solid materials (solid-state nanopores).

  • A protein nanopore is set in an electrically resistant polymer membrane. An ionic current is passed through the nanopore by setting a voltage across this membrane. If an analyte passes through the pore or near its aperture, this event creates a characteristic disruption in current (as shown in the diagram below). Measurement of that current makes it possible to identify the molecule in question.
