Timothy Phillips, Ph.D., and team at the Texas A&M University SRP Center developed therapeutic sorbent technology to reduce the ability of hazardous chemicals to harm the body. These edible sorbents decrease exposures by binding to chemicals, like per- and polyfluoroalkyl substances (PFAS), in the intestines.

Building on decades of research, the team found the clay-based edible sorbents can strongly bind specific PFAS and mixtures of PFAS and protected against toxicity.

They are also exploring how these sorbents can be used to clean up PFAS-contaminated sites or reduce their uptake by plants.

Learn more about the team’s work in this trainee spotlight video.

Technology Nutrient-amended montmorillonite clay.
Innovation Builds on more than 30 years of research developing and testing broad-acting sorbent materials to bind hazardous chemicals more effectively. Can be added to food and water to reduce exposure to harmful contaminants, including in the aftermath of disasters.
Contaminant PFAS including PFOA (perfluorooctanoate), PFOS (perfluorooctanesulfonate), GenX (hexafluoropropylene oxide), and PFBS (perfluorobutane sulfonic acid)
