Nanopareil [nano-puh-rel] produces cutting-edge separation media composed of functionalized nanofibers. The product is manufactured from a randomly overlaid mat 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 biopharmaceutical, water treatment, desalination, blood products, and air purification industries.
What is 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.
Benefits of Nanopareil
Over $110 million annual savings for a single biopharmaceutical product
Over 30% reduction in overall operating costs per kg of product
Over 10-times faster throughput – shorter processing times, reduced labor, more efficient use of limited manufacturing space
Over 10-times higher capacity – lower materials requirements
Over 5-times less water consumption – reduced loads on purified water systems
Over 5-times less waste generation – more environmentally friendly production processes and lower waste disposal costs
Off-the-shelf installation into the manufacturing processNo capital investment required for switching from existing packed bed operations to nanofiber based adsorption media
Net $1.00/gallon through recovery of high-value co-products from advanced bio-fuels
Capturing and purifying fermentation inhibitory compounds

Nanofiber Separations, LLC was born out of a project sponsored by the National Science Foundation (NSF) that began in 2006. 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, Nanofiber Separations was organized as a limited liability company under the laws of the State of South Dakota in October, 2011. In February 2014, Nanofiber Separations 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.
In July of 2015 Nanofiber Separations, LLC officially changed its name to Nanopareil, LLC.
