Our technology enables early, accurate, point-of-care detection of viruses, bacteria, and other threats to human health.


We enable low cost, on-site, rapid identification of threats to crops, helping protect the world's food supply.


We can help protect against threats to the environment through early identification of pathogens in the field.


Our technology platform is based on solid-state nanopores, nano-scale holes formed into silicon microchips.  Particles passing through these pores generate measurable electrical events.

By detecting biomarkers unique to the DNA or RNA of a target pathogen, we can determine not only its presence, but also its quantity within a fluid sample using the electronic nanopore signal. This is critical for optimal response planning, as well as monitoring of disease progression and treatment efficacy.

We are incorporating this technology into a portable handheld diagnostic device.  The device will enable rapid, point-of-need, low cost, accurate, sensitive, quantifiable detection of the targeted pathogen.


Adam Hall

Adam Hall

Chief Scientific Officer
Adam Hall received his training in physics and materials sciences at the University of North Carolina at Chapel Hill, where he performed research under  Sean Washburn on nanoelectomechanical systems incorporating individual nanomaterials  He then spent the next three years as a postdoctoral researcher at Technische Universitat Delft in the Netherlands, where he performed experiments on solid-state nanopores in the lab of Cees Dekker. From 2010-13, he was an Assistant Professor of Nanoscience at the Joint School of Nanoscience and Nanoengineering in Greensboro, NC, where he earned awards for both his research activities and teaching. He joined the faculty of the Virginia Tech-Wake Forest School of Biomedical Engineering and Sciences in August of 2013 as an Assistant Professor in the Wake Forest University School of Medicine.

Outside of the lab, Adam enjoys finding new music, reading, illustration, and spending time with his wife and two children.
