RAPID CITY – Gamma Biosciences has announced that it acquired South Dakota Mines’ spinoff company Nanopareil, LLC. 

Nanopareil was founded on the campus of South Dakota Mines thanks to National Science Foundation (NSF) funded research. Nanopareil produces revolutionary filters that have a range of biopharmaceutical applications including significantly reducing the cost and manufacturing time for lifesaving vaccines and medicines. The company will keep its current facility in Rapid City.

Gamma Biosciences is a life sciences tools platform created by KKR. Gamma’s mission is to build a leading player in next-generation bioprocessing for advanced therapies by acquiring high-potential businesses with outstanding technology and accelerating their growth.

“This might be the first time a product developed by research at a South Dakota university has seen an acquisition of this magnitude and importance,” says Joseph Wright, the associate vice president for research and economic development. “This would be a big deal for any major research university, but for a smaller school like South Dakota Mines, it’s virtually unprecedented. This demonstrates that Mines researchers can be world leaders in research and innovation.”

This story of success begins in 2006, when NSF saw promise in the work of South Dakota Mines’ professors Todd Menkhaus, Ph.D. and Hao Fong, Ph.D. NSF funded their research into potential uses for polymer nanofibers that are one thousand times smaller than human hair. Fong and Menkhaus found that by spraying nanofibers into multiple layered mats, they could create a new type of filter material that reduces the costs of purifying vaccines and medications so that they are more accessible and more economical around the globe.

By 2011, realizing the commercial potential for their new product, Menkhaus and Fong formed a company now named Nanopareil, LLC to help carry their innovation into the marketplace. In 2014, NSF awarded them a Small Business Innovation Research grant, and the company won the South Dakota Governor’s Giant Vision Awards. In 2017, Nanopareil was named the Buzz of BIO at the BIO International Convention and took first place in the Technologies of Tomorrow competition. By 2019, Nanopareil moved into the Ascent Innovation building, Rapid City’s high-tech business incubator, and expanded to a second lab in Sioux Falls to further their product research and development.

Gamma Biosciences will operate Nanopareil as part of its existing subsidiary, Astrea Bioseparations. The acquisition assures further success in the marketplace for the revolutionary products developed by Nanopareil. In a company press release, Gamma Biosciences states that “Gamma plans to invest substantially in further productization and technology development, application development and customer support as it establishes Nanopareil as a key platform within Astrea’s growing range of products.” Craig Arnold, CEO of Nanopareil, LLC, says, “The Astrea team has a strong track record of bringing innovative new products to the market. With their leadership and capabilities, Nanopareil will be well positioned to become the next-generation market leader.”
