A nanopore is a tiny hole in a thin membrane with a diameter of around a billionth of a meter, or about the width of a single DNA molecule. The potential applications of these nanopores are so diverse - from medicine to information technology (IT) - that they could have a major impact on our daily lives. Now a team of researchers at the University of Ottawa is democratizing entry into the field of nanopore research by offering up a unique tool to accelerate the development of new applications and discoveries.
The innovative T.-Cossa Lab, which studies applied single-molecule biophysics, came up with the idea to provide the research community with the protocols, hardware designs, and software required to fabricate solid-state nanopores in a fast, low cost, and completely automated fashion. This method is now available in the online journal Nature Protocols .
The move is a boon for researchers developing diagnostic and sequencing applications in health, life sciences, and IT, where being able to detect and identify single biological molecules like proteins or DNA with the exacting precision of a nanopore is needed.
For the first time, we are making our unique nanopore fabrication tool freely available. We opted to offer our patented nanopore fabrication technology to the research community for free, to help disseminate it and expand the field of nanopore research."

Solid-state nanopores are now well established as single-biomolecule sensors which hold enormous promise for fast and low-cost sensing and sequencing applications, including rapid identification of pathogens, biomarker quantification for precision medicine, metagenomics, microbiome analysis, and cancer research. However, until recently, this promise had been stifled by the expensive, labor intensive, and low-yield methods by which pores were fabricated. To address this problem, Professor Tabard-Cossa and his team pioneered a cheap and scalable solid-state nanopore fabrication method in 2012 called controlled breakdown (CBD), which has since become the method of choice by which solid-state nanopores are fabricated by research groups around the world.
