Nanopareil produces cutting-edge separation media composed of functionalized nanofibers. The product is manufactured from a randomly overlaidmat of electrospun nanofibers, which provide  a unique separation medium capable of both size-based as well as adsorptive separation mechanisms.   The highly advanced and proprietary formulation provides the opportunity to greatly enhance process efficiencies and economics in the antibody, vaccine, and blood product purification markets.

Benefits of Nanopareil

Purification modules produced by Nanopareil offer major advantages over commercial microfiber separation media and packed bed adsorption resins. Specifically, our nanofiber products provide an enormous amount of specific surface area along with a controlled porosity and offers modular, off-the- shelf installation into existing manufacturing processes.

These three combined features allow for major production advantages, including:

  • Faster throughput, lower operating pressure
  • Higher adsorptive capacity
  • Less water consumption, less waste generation
  • Greatly improved manufacturing simplicity and reproducibility.

Our Story

Nanofiber Separations, LLC was born out of a project sponsored by the National Science Foundation (NSF) that began in 2006. In July of 2015 Nanofiber Separations, LLC officially changed its name to Nanopareil, LLC. During this five-year project, the company co-founders, Dr. Todd Menkhaus and Dr. Hao Fong, determined that a commercially available nanofiber product would be a significant improvement over existing adsorption and size-based separation media in several, high-value market segments. With this major unmet need for advanced purification devices confirmed in the marketplace, Nanopareil was organized as a limited liability company under the laws of the State of South Dakota in October, 2011. In February 2014, Nanopareil was awarded a National Science Foundation (NSF) Small Business Innovation Research (SBIR) Phase II Grant and in April of 2014, Nanofiber Separations received statewide recognition by winning the South Dakota Governor’s Giant Vision Business Plan Competition.

Leadership

D. Craig Arnold

President & Chief Executive Officer

Craig Arnold’s leadership experience spans more than 30 years, including technology start-ups, biotechnology and biofuels, as well as leadership positions in philanthropy, computer technology and aerospace industries. Prior to joining Nanopareil, Arnold was President & CEO of Permara, LLC, a South Dakota biotech start-up that commercialized a novel renewable antimicrobial technology. As CEO of Plymouth Energy, Arnold led the $100M debt/equity financing, construction, and production start-up of a Midwest based 50 million gallon a year (MGY) biofuels plant. Craig was a Director at the Bill and Melinda Gates Foundation, where he was responsible for the Foundation’s access to a technology program that was expanded worldwide. Arnold held leadership roles at Northrop-Grumman and Rockwell International (Boeing) on the B2 Stealth Bomber and B1B Lancer aircraft programs respectively. Mr. Arnold holds a commercial pilot’s license and is a multi-engine and instrument instructor pilot.
