Image from Licence Details: Fabricating arrays of nanopores self-aligned with on-chip nanostructures

Applications: DNA Sequencing, Data Storage, Analyte Detection, Biosensing

Researchers at the University of Oxford have developed a new method to fabricate individual or arrays of nanopores self-aligned with on-chip electrodes.

Features Benefits
  • Nanopores are created by applying a breakdown voltage between an on-chip electrode and an electrolyte solution in contact with the other side of the membrane.
  • Can be performed using inexpensive equipment.
  • Doesn’t require a highly experienced user and the process can be automated.
  • Process is rapid compared to current techniques.
  • The applied electric field is localised to the on-chip electrode.
  • Can independently fabricate and localise multiple nanopores simultaneously.
  • Serves as an extension of controlled breakdown technique where nanopores can be precisely self-aligned with complementary nanostructures.
  • No additional equipment or fabrication steps are needed for alignment with on-chip electrodes.
  • Creates nanopores in the electrolyte environment in which measurements will be performed.
  • The complementary nanostructures can provide alternate detection modalities to ionic current based sensing typically used for nanopore sensing.
  • Biosensors can be developed with increased device bandwidth, higher device densities, and higher sensitivity to additional molecular properties.
