The U.S. Environmental Protection Agency (EPA) is seeking applications for research to develop and demonstrate nanosensor technology with the potential to detect, monitor, and degrade per- and polyfluoroalkyl substances (PFAS) in groundwater or surface water that may be used as drinking water sources. EPA states that advances in nanoscience and nanotechnology have the potential to address the challenges of detection and treatment of PFAS-contaminated waters. Because nanomaterials are smaller in size, larger in surface area, and more easily manipulated and dispersed in water than conventional materials, they are useful for environmental sensing and management. According to EPA, using nanotechnology may help to build better environmental sensors by reducing cost, improving efficiency, and increasing selectivity. EPA notes that nanotechnology may also be used to degrade PFAS in a way that does not create toxic byproducts. Applications must address both of the following research areas:

• Develop and demonstrate nanosensor technology to detect and monitor PFAS in drinking water sources; and

• Develop and demonstrate nanosensor technology with functionalized catalysts to degrade PFAS.

EPA states that it is “seeking projects with expected results that can be practically applied in real-world settings and potentially transform environmental monitoring and management.” EPA will hold an informational webinar on August 29, 2024. Applications are due November 13, 2024.
