Environmental water remediation is currently a $6 billion per year industry with 5,000 to 12,000 newly discovered remediation sites per year. Over the next several decades, private industry and federal, state and local governments will commit billions of dollars annually to clean up sites contaminated with risky waste products.


Chlorinated solvents are common additives in paint thinners, dry cleaning solutions, degreasers, and were formally associated with gas stations and chemical manufacturers. These pollutants were historically dumped into the groundwater and, despite more recent regulations, are still commonly found pollutants in our groundwater today.  Unfortunately, people who are exposed to such compounds can experience a number of serious health effects including organ damage, impaired fetal development, cancer, and death.


NanoFex’s technology is based on the in-situ chemical reduction (ISCR) of chlorinated compounds and certain heavy metals in soil and groundwater using a multifunctional particulate system (MPS) containing zero-valent iron nanoparticles embedded on carbon microspheres. The technology uses an aerosol based process to rapidly prepare the iron-carbon composite. Source materials can be made from inexpensive and innocuous precursors (sugar, waste crustacean shells, iron salts) and are intrinsically environmentally benign.

NanoFex wins $50,000 New Orleans Water Challenge 03/21/2011

NanoFex Ignites World Class Talent With New Headquarters In New Orleans Bioinnovation Center

- Feb 15th, 2012 -
New Orleans based biotech startup NanoFex, LLC, a privately held biotech company providing technologies that more cost effectively remediate environmental contamination challenges, announced its launch at the New Orleans BioInnovation Center. Tulane’s Executive Director of Technology Transfer and Intellectual Property Development, John Christie, and NanoFex CEO, David


Culpepper, signed an option-to-license agreement that grants NanoFex the exclusive right to produce carbon microspheres that use nano-iron particles for cleaning environmental contamination. Using an environmentally sustainable nanotechnology derived from Louisiana cane sugar, crab and crawfish shells, NanoFex will sequester and break down groundwater contaminants such as chlorinated solvents, arsenic and heavy metals.

NanoFex Technology Utilizes Crawfish Shells And Sugar Cane To Clean Groundwater

- July 11th, 2012 -
Most major construction projects require an environmental assessment. Using Geoprobe machinery, companies like Walker-Hill Environmental


drill deep into the earth, pound in a sample tube and pull out layers of soil. Then it’s up to someone like NanoFex’s David Culpepper to analyze it. He’s looking for “changes in soil type and geology, presence of contamination such as gasoline or diesel, hydrocarbons.”

NanoFex Wins Water Challenge With Plan To Decontaminate Ground Water

- March 22, 2011 -
NanoFex’s winning idea revolves around the widespread problem of contaminated groundwater (the water many people drink). Using Louisiana sugarcane and crab and crawfish shells, NanoFex makes a product that binds to contaminates like arsenic, chlorinated solvents and heavy metals, and breaks them down into harmless carbon dioxide and water. The technology was developed at Tulane University’s Department of Chemical and Biomolecular Engineering, under the direction of engineering professor Dr. Vijay John.”

NanoFex: Part Of Louisiana’s Diverse Tech Mecca

- July 11th, 2012 -
“New Orleans has a culture for innovation, specifically within education,” said Meghan Mclain, Communications Lead for Dash, on why New Orleans has been a welcoming place for

education technology entrepreneurs. “The teachers and schools are quick to adapt to new and innovative ideas. It’s as if the idea of ‘slow to warm up’ doesn’t exist here.” NanoFex is rapidly becoming an integral part of this post-Katrina boom in tech development in the city.

NanoFex CEO David Culpepper Awarded Tulane Challenge Prize

- July 11th, 2012 -
Ventures with strong connections to Tulane University and the A. B. Freeman School of Business were big winners in last week’s 2012 New Orleans Entrepreneur Week, an event highlighting


the city’s thriving startup community. Companies founded by Tulane staff, students or alumni won three of the five major contests, each winning a $50,000 cash prize, while many more participated as contestants throughout the week.
