Recent Reports from University of Ottawa Highlight Findings in Life Science Research

June 17, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Life Science Research is the subject of a report. According to news reporting originating in Ottawa, Canada, by NewsRx journalists, research stated, "Nanofabrication techniques for achieving dimensional control at the nanometer scale are generally equipment-intensive and time-consuming. The use of energetic beams of electrons or ions has placed the fabrication of nanopores in thin solid-state membranes within reach of some academic laboratories, yet these tools are not accessible to many researchers and are poorly suited for mass-production."

The news reporters obtained a quote from the research from the University of Ottawa, "Here we describe a fast and simple approach for fabricating a single nanopore down to 2-nm in size with sub-nm precision, directly in solution, by controlling dielectric breakdown at the nanoscale. The method relies on applying a voltage across an insulating membrane to generate a high electric field, while monitoring the induced leakage current. We show that nanopores fabricated by this method produce clear electrical signals from translocating DNA molecules."

According to the news reporters, the research concluded: "Considering the tremendous reduction in complexity and cost, we envision this fabrication strategy would not only benefit researchers from the physical and life sciences interested in gaining reliable access to solid-state nanopores, but may provide a path towards manufacturing of nanopore-based biotechnologies."
